Answer:
625 seconds and 10 minutes
Step-by-step explanation:
distancs=S=5km=5000m
average speed=v=8m/s
time taken=t=?
as we know that
average speed=
average speed×time taken=distance covered
here we have to find the time taken
time taken=
time taken=
time taken=625seconds
now we convert seconds into minutes

10 minutes
