what is the rate of each cyclist if one is 7km/h slower than the other and they are 135 km apart after 3 hours?

Question

rate of the slower cyclist is in km/h, as well as the rate of the slower cyclist 

Answer 1

Assuming, the speed of the slower cyclist is X km/h

then the speed of the other one is (X+7) km/h

also, assuming they're going to the opposite direction

 

According to the question,

 

(X+7+X)*3=135

=> 6X=114

X=19

 

So the rate of the slower cyclist is 19 km/h

and the other one has a speed of 26 km/h
