Sam and Nora leave their business office at the same time. Sam drives north at 35km/h, Nora drives south at 47km/h. How long until they are 50 km apart?

_award brainliest if helped!! 
Difference in speed = 47+35 = 82km/h 
(They are going in opposite directions)
So they are drifting apart at rate of 82km/h
Time taken to be 50km apart = 50/82 = 0.6 h
