The number of the **degrees **of a point on the **edge **of the tire moving in 1 seconds will be 2700°.
What is Algebraic expression ?
Algebraic expressions are the idea of expressing numbers using letters or **alphabets **without specifying their actual values. The basics of algebra taught us how to express an unknown value using **letters **such as x, y, z, etc. These letters are called here as variables. An algebraic expression can be a combination of both **variables **and constants . Any value that is placed before and multiplied by a variable is a coefficient .
A tire is **rotating **450 times per minute.
Convert **RPM **into RPS . Then we have
⇒ 450 / 60
⇒ 7.5 times per second
Then the number of the **degrees **of a point on the **edge **of the tire move in 1 seconds will be :
⇒ 7.5 x 1 x 360°
⇒ 2700°
The number of the **degrees **of a point on the edge of the tire moving in 1 seconds will be 2700°.

The question asks: A tire rotates 450 times per min. Through how many degrees does a point on the edge of the tire move in 1 second? To solve this, we first convert the rotation per minute to rotation per second, then calculate the degrees of rotation.
Convert rotations per minute (rpm) to rotations per second (rps): 450 rpm ÷ 60 seconds = 7.5 rps.
Since one full rotation equals 360 degrees, we multiply the rotations per second by 360 to find the degree of one rotation in one second: 7.5 rps × 360 degrees = 2700 degrees.
Therefore, a point on the edge of the tire moves through 2700 degrees in one second.
A point on the edge of a tire rotating at 450 times per minute moves through 2700 degrees in one second. This is calculated by converting RPM to RPS and multiplying by the degrees in a full revolution. In this case, 450 RPM converts to 7.5 RPS, leading to a total of 2700 degrees in one second.
