Answer:
7 km/hr and 13 km/hr
Step-by-step explanation:
because in this case we divide the total distance covered by the total time taken than the answer would be 10 km /hr but according to the question we have to subtract 3km/hr and also have to add 3km/hr.
there for there average speed of friends with wind was 7 km/hr
and friends without wind will be 13 km/hr
