Question

a car running at uniform speed covers 126 km in 3 hours how much time will it take to cover a distance of 462 km​

Answer 1

Answer:

11 hours

Step-by-step explanation:

we first find the speed

find speed in 1 hour by unitary meathod

3 hours -------- 126 km

1 hour ---------126/3 = 42 km

there fore speed = 42 km/h

now to find the time taken for 462 km, use speed = distance/time

42 = 462 / t

=> t = 462/ 42

=> t = 11

there fore it takes 11 hours
