dorabella and guillermo and 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 cnoe and 9 mph. How many hours will it take guillermo to catch dorabella

Answer 1

Let's first calculate the relative speed between Dorabella and Guillermo.

Since they are traveling in the same direction, the relative speed would be the difference in their speeds:
Relative speed = 9 mph - 7 mph = 2 mph

Now, we can calculate the time it takes for Guillermo to catch Dorabella using the formula:

Time = Distance / Relative speed

Distance = 4 miles (as Dorabella is 4 miles ahead)
Relative speed = 2 mph

Time = 4 miles / 2 mph = 2 hours

Therefore, it will take Guillermo 2 hours to catch Dorabella.
