Pesawat A terbang berangkat dari Jakarta ke Surabaya dgn kec. 500 km/jam pada jam 08.00 WIB. Pesawat B terbang berangkat dari Surabaya ke Jakarta dgn kec. 600 km/jam pada jam 07.45 WIB. Jarak antara Jakarta Surabaya = 1.000 km. Pada jam berapa ke 2 pesawat tersebut akan berpapasan? (Asumsi lintasannya sama, kecepatan dan arah angin diabaikan).

Disadvantages of Using Animation in Advertising
While animation can be a powerful tool for storytelling and capturing attention in advertising, it does have its own set of disadvantages. One major downside is the potential for high costs associated with producing high-quality animation. Additionally, animation that is not well-executed can potentially alienate or confuse the target audience rather than engage them. Moreover, there's a risk of over-reliance on visual flair rather than the message, which can dilute the effectiveness of the advertisement.
Advantages and Disadvantages of Using Animation in Education
Animation in education can enhance learning by providing visual representation of concepts that might be difficult to understand through text alone. However, there are also disadvantages. For instance, overuse of animation can be distracting to students, and the creation of educational animations can be time-consuming and costly. Additionally, not all topics lend themselves well to animation, and there can be a mismach between the complexity of the subject and the simplicity of the animation.
Advantages and Disadvantages of Using Animation in Entertainment
In entertainment, animation provides the freedom to create any imaginable world and characters, which can be a strong advantage. It can also simplify the depiction of complex scenarios or events. However, one of the key disadvantages is that creating high-quality animation is often resource-intensive. Furthermore, audience fatigue can occur if there's an oversaturation of animation content in the market, and some audiences may not take animated content as seriously as liv-action.
Understanding the Use of Presentation Aids
Presentation aids, such as PowerPoint slides, can effectively visualize concepts and simplify the delivery of information. Yet, they can also oversimplify information and inhibit critical thinking, as criticized by Franck Frommer and Edward Tufte. The strategic use of presentation formats, whether slides, videos, or other multimedia aids, comes with the responsibility to enhance the content's delivery without oversimplifying or detracting from the core message.
Animation offers both advantages, like enhanced engagement and creativity, and disadvantages, such as high costs and potential distraction from core messages across advertising, education, and entertainment. Effective use requires careful consideration to balance visual appeal with the intended message. Understanding these factors can help in making informed decisions about utilizing animation in different contexts.

Jawab:Pukul 08.46 WIBPenjelasan dengan langkah-langkah:Untuk mencari waktu berpapasan dua pesawat yang bergerak saling mendekat, gunakan konsep jarak = kecepatan × waktu.Diketahui:Jarak Jakarta–Surabaya = 1000 kmPesawat A:Berangkat dari Jakarta ke SurabayaKecepatan = 500 km/jamBerangkat pukul 08.00 WIBPesawat B:Berangkat dari Surabaya ke Jakarta Kecepatan = 600 km/jamBerangkat pukul 07.45 WIBTentukan Selisih waktu keberangkatan:Pesawat B berangkat lebih dulu 15 menit = 0,25 jam sebelum pesawat A.Dalam 0,25 jam, pesawat B menempuh:[tex]\text{Jarak tempuh B} = 600 \times 0,25 = 150 \text{ km}[/tex]Jadi, saat pesawat A mulai terbang (pukul 08.00), jarak yang tersisa antara mereka = 1000 - 150 = 850 kmGerak pesawat saling mendekatGabungan kecepatan pesawat A dan B:[tex]v_{\text{relatif}} = 500 + 600 = 1100 \text{ km/jam}[/tex]Waktu untuk berpapasan:[tex]t = \frac{\text{jarak sisa}}{v_{\text{relatif}}} = \frac{850}{1100} \approx 0{,}7727 \text{ jam}[/tex]Konversi ke menit:[tex]0{,}7727 \times 60 \approx 46{,}36 \text{ menit} \Rightarrow \approx 46 \text{ menit}[/tex]Kedua pesawat akan berpapasan sekitar 46 menit setelah pukul 08.00, yaitu pada:Pukul 08.46 WIB.
