Question

A car travelling at an average speed of 100km/h covers a distance in 3hrs 20minutes.At what constant speed must the car travel to cover the same distance in 2hrs 40 minutes

Answer 1

Answer:

125 km/hr

Explanation:

Speed =distance /time

Speed=100km/hr

time =200 minutes =200/60=10/3 hr

Distance =speed *time

Distance =100*10/3=333.33 KM (1)

The car travel to cover the same distance in 2hrs 40 minutes

Find speed

Time =160/60=8/3 hrs

Speed =(100*10/3)/(8/3)

=(100*10*3)/(8*3)

=100*10/8

=125km/hr
