Question

The Clarke Family went sailing on a lake. Their boat averaged 6 kilometers per hour. The Rourke Family outboard runabout for a trip on the laked for the same amount of time. Their boat averaged 14 kilometers per hour. The Rourke family traveled 20 kilometers farther than the Clarke Family. How many hours did each family spend on the lake

Answer 1

d = r · t

d_Clarke = 6t

d_Rouke = 14t

d_Rouke = d_Clarke + 20

14t = 6t + 20

 

Can you solve for t and answer?
