A car leaves a city 20 minutes after a truck leaves the same city. The truck is traveling at an average speed of 60 km/h, and the car is traveling at an average speed of 80 km/h. How long will it take for the car to overtake the truck?

Answer :

Final answer:

The car will overtake the truck in 15 minutes.

Explanation:

To find out how long it will take for the car to overtake the truck, we need to consider the relative distance covered by both vehicles. Since the truck has a head start of 20 minutes, it will have already covered a certain distance when the car starts. Let's calculate the distance covered by the truck in 20 minutes:

Distance = speed × time

Distance = 60 × (20/60) = 20 km

Now, let's find out how long it will take for the car to cover this distance:

Time = distance / speed

Time = 20 / 80 = 0.25 hours = 15 minutes

Therefore, it will take the car 15 minutes to overtake the truck.
