Question

Police chases a driver. The police is 1 mile behind the driver. The speed of the police is 90 mph, and the speed of the chased car is 85 mph. How long will it take for the police to catch up with the car?

Answer 1

0.20 hour

Explanation:

According to the problem, computation of the given data are as follows,

Speed of police = 90 mph

Speed of chased car = 85 mph

Distance to be chased = 1 mile

So, we can calculate the time to catch by using following formula:

Time required = Distance between two cars ÷ (Speed of Car A - Speed of Car B)

= 1 ÷ ( 90 - 85)

= 1 ÷ 5

= 0.20 hour
