Question

just confused

 

Answer 1

distance/time = rate, distance = time x rate

 

The distances are equal.  Paul bikes 3 hours to reach his favorite beach he bikes 2 mph faster on the way backsothe trip back only takes 2.5 hours 

 

3 hr. x rate = 2.5 hr x (rate + 2)

 

3r = 2.5(r + 2)

 

3r = 2.5 r + 5

 

.5r = 5

 

r = 10 mph
