answer
I. 2hrs
ii. 142km
step-by-step answer
since the car has a uniform speed
it travels 90km in 2½hrs
so to know the time taken for 72km
we will divide 90 by 2½ = 36km/h
:- time taken for distance 72km= 72÷32= 2hrs
ii. since the car travels with uniform speed, and we know that it cover a distance of 72km in 2hrs
:- in 4hrs = 2×72km = 142km.
