Question

two cars leave a town at the same time in opposite direction at 50 km per hour and 60 km per hour in how many hours will they be back 55 km apart

Answer 1

Heya!!!!
Speed of First car(s1) = 50km/h
Speed of second car(s2) = 60km/h
Total speed of both cars = s1 + s2
= 50+60
= 110km/h
Distance = 55km
Time = ???
So ,Time = Distance /speed
Time = 55/110
= 1/2 hours.
