Ilya and Anya each can run at a speed of 9.00 mph and walk at a speed of 3.80 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.

Part A ( I solved this part)

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

Express your answer numerically, in minutes.

tAnya =
56.1

minutes
Part B ( I solved this part)

Find Anya's average speed.

Express Anya's average speed save, Anya numerically, in miles per hour.

save, Anya =
5.34

mph
Part C (NEED HELP)

How long does it take Ilya to cover the distance?

Express the time tIlya taken by Ilya numerically, in minutes.

tIlya = minutes
Part D (NEED HELP)

Now find Ilya's average speed.

Express Ilya's average speed save, Ilya numerically, in miles per hour.
