Solve the all parts of following question given below:

Question: Ilya and Anya each can run at a speed of 8.30mph and walk at a speed of 3.90mph. They set off together on a route of length 5.00miles . 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: How long does it take Anya to cover the distance of 5.00miles? Express your answer numerically, in minutes.

Part B: Find Anya's average speed. Express Anya's average speed save,Anya numerically, in miles per hour.

Part C: How long does it take Ilya to cover the distance? Express the time tIlya taken by Ilya numerically, in minutes.

Part D: Now find Ilya's average speed. Express Ilya's average speed save,Ilya numerically, in miles per hour.
