Question

suize can run 2.5mile per hr faster then jeff. in the time it takes suize to run 6 mile jeff runs 4 mile find the speed of each runner

Answer 1

If you would like to know the speed of each runner, you can calculate this using the following steps:

6 miles ... x + 2.5 mile per hr (Suize)
4 miles ... x mile per hr (Jeff)

6 * x = 4 * (x + 2.5)
6 * x = 4 * x + 4 * 2.5
2 * x = 4 * 2.5
2 * x = 10
Jeff: x = 5 mile per hr

Suize: x + 2.5 = 5 + 2.5 = 7.5 mile per hr

Suize runs 7.5 mile per hr, and Jeff 5 mile per hr.
