Question

A express train covers 60km in one hour. How much time will it take to cover 90 km?

Answer 1

Answer:

Time taken to cover 60 km = 1 hour. Time taken to cover 1 km = 1/60 hour. Time taken to cover 300 km = 1/60 × 300 hour. Therefore, time taken to cover 300 km is 5 hours.

Answer 2

Answer:

it will take 1.5 hour to cover 90km

Step-by-step explanation:

distance covered = 60 km

time taken = 1 hour

so speed = d/t

=>60/1hour

=> 60 km per hour

time taken to cover in 90km = d/s

90/60

=>1.5 hour
