How long does it take anya to cover the distance of 5.00 miles?

Here is the full information about the question. Ilya and Anya each can run at a speed of 8.50mph and walk at a speed of 3.50 mph. They set off together on a route of length 5.00 miles. Anya walks half of the distance and runs the other half, while Ilya walks half of the time and runs the other half.

the calculation would be:

t = d / s

t = 2.5 (half of the total distance) / 8.5 (speed of running)

This is. 294 hours which is about 1058s ...

for the walking part ...

t = d / s

t = 2.5 / 3.5

t = 5/7hours = 2571 s.
