Question

Two cars begin traveling along the road at speeds of 70km/h and 80km/h recpectively. What is the distance between two cara after five hours? 

Answer 1

Assuming they start from the same location at the same time:

 

(70 km/hr)(5 hrs) = 350 km

(80 km/hr)(5 hrs) = 400 km

 

Distance between them after 5 hours:  400-350 = 50 km
