Answer:

Step-by-step explanation:

Alright, lets get started.

Suppose they take t minutes to meet each other.

Distance covered by first friend in t minutes, = 0.2 *t=0.2∗t

Distance covered by second friend in t minutes , =0.15 *t=0.15∗t

Total distance is given as 7, so

0.2 t + 0.15 t = 70.2t+0.15t=7

0.35 t = 70.35t=7

t = 20t=20

means after 20minutes they will meet.

SO. the average speed is 10m: Answer
