Problem- Ilya and Anya each can run at a speed of 7.90mph 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 Ilya to cover the distance?

Part B- Now find Ilya's average speed.

Please be very comprehensive in your answer and do not omit any steps
