Question

Chapter Speed, Time and Distance

Q1. On a 450 km trip to Manali, Tarun's driving speed was 40 km/h for half of the trip. If he completes the trip in 12 hours, find his driving speed for the rest of the journey.?​

Answer 1

Answer:

35.29

Step-by-step explanation:

Distance travelled by tarun for 40 km/h = 450/2 = 225

time taken by tarun to travel that

time = d/s

t = 225/40 = 45/8 hours

45/8 hours

time taken to travel next half = total time - timr

= 12-45/8

=51/8

speed = d/t

225/51/8

= 225*8/51

=1800/51

=600/17

=35.29
