Answer:
6.9444 m/s
Explanation:
total distance covered=2 km+3km
=5 km
total time taken = 4min + 7 min + 1 min
=12 min
(as we would add his rest also)
avg speed = total distance covered ÷ total time taken
= 5 ÷12 km/min
= 5 X 1000 ÷ 12 X 60
calculate it and get your answer as 6.9444444
This is the answer
