Question

if a car is at velocity of 20 miles per hour if the car traveled 120 km in 3 hours at a consistent acceleration what is its final velocity

Answer 1

Explanation:

Let distance from A to B be x

Time for travel from A to B= x/20

Time for travel from B to A= x/30

Hence,speed for total distance 2x is:

30

x

+

20

x

2x

=

5x

2x×60

=24 km\hr
