Three hours after the bus starts out, it's 150 miles ahead of the truck. Then the truck starts out, and it gains (65-50)=15 miles on the bus every hour. If neither of them ever stops for anything, the truck will catch up to the bus in ( 150/15 ) = 10 hours. . . . (The hint is useless.)
To calculate the time it takes for the truck to catch the bus, we first note that the bus travels 150 miles in the 3 hours before the truck starts. Since the truck travels at a relative speed of 15 mph faster than the bus, it closes the gap at a rate of 15 miles per hour. By dividing the initial distance of 150 miles by the relative speed, we find it takes the truck 10 hours to catch the bus.
We are tasked with solving a problem where we need to find out how long it takes for a truck to catch a bus that departed three hours earlier. The bus is moving at a constant speed of 50 mph, and the truck is pursuing it at 65 mph.
To figure this out, we can use the concept of relative speed and the distance covered by the bus in those three hours. The bus covers 150 miles (50 mph * 3 hours) before the truck starts. Since the truck is moving 15 mph faster than the bus (65 mph - 50 mph = 15 mph), it is closing the distance by 15 miles every hour.
We now set up an equation to find the time t it takes for the truck to cover the 150 miles gap: 150 miles = 15 mph * t
Solving for t gives us: t = 150 miles / 15 mph t = 10 hours
Therefore, it will take the truck 10 hours to catch up to the bus.
The truck takes 10 hours to catch up to the bus after it starts its journey, having a 150-mile head start from the bus's earlier departure. This is calculated by using the relative speed between the two vehicles. The bus travels 150 miles in the first 3 hours while the truck travels 15 miles per hour faster than the bus after it starts.
