Question

a car is travelling a speed of 252/2 km/ h . how much time it will take to travel the distance of 200km100m

Answer 1

speed = 252/2 =126km/h
distance = 200 + 100/1000 km =200.1km
time= 200.1/126 = 1.5881 hours

Answer 2

a car travel 252/2 km/h
If 1 km = 1000 m
So, 252 km = 252*1000
                    =252000m
252000                 2h

200100                 x

252000x   =    200100*2
so, x =400200/252000
so, x=1.588

So, the car will cover 200km100m in 1.588 h
