Answer:



Step-by-step explanation:
From the question we are told that
Run speed of Ilya and Anya

Walk speed of Ilya and Anya

Total distance

Anya Walks 1/2d and runs 1/2d
ilya walks 1/2t and runs 1/2d
Generally the distance walked by Ilay k is mathematically given by
Since ilya walks 1/2t and runs 1/2t
Therefore


Therefore llay runing distance is m

a)Generally the Time walked by Anya
is mathematically given by
Anya Walks 1/2d and runs 1/2d
Therefore






b)Generally the average speed of Anya S_A is mathematically given as



Generally the time taken b y llay
is mathematically given by
