Question

The distance between delhi and bhopal is 420 km. Andhra express takes 7hrs 20min to cover distance. Find the speed of the train

Answer 1

$speed = distance \div time$

distance = 420×1000

=42000m (1km = 1000m)

time= 7×60×60 = 25200s

25200+20 = 25220

by substituting value in formula

speed = 42000/25220

=1.6m/s
