Dorabella and Guillermo are rowing on the same river in the same direction. Dorabella is rowing her canoe at 7 mph and is exactly 4 miles ahead of Guillermo, who is rowing his canoe at 9 mph. How many hours will it take Guillermo to catch up to Dorabella?

Answer :

Answer:

the number of hours taken is 2

Step-by-step explanation:

The computation of the number of hours taken is shown below:

As we know that

Distance = travel time × speed

The Guillermo to catch Dorabella be t = T

So the equations would be

9T = 4 + 7T

9T - 7T = 4

2T = 4

T = 2 hours

hence, the number of hours taken is 2
