Question

If a train travels between two cities in 3 hrs at an average speed of 65 miles per hour, how long would it take at an average speed of 80 miles per hour?

Answer 1

In case1,

speed=65

time taken=3

distance=speed×time taken

=65×3

distance=195miles

in case two

speed=80

distance=195

time taken=195/80

time taken=2.43 hours
