Answer:
We need to convert speed into m/s because in this question , we are going to take SI units for all quantities.
Speed= 20 × 5/18=0.5 m/s
We need to find time.
Time = distance/speed
Time= 400/0.5 =800 seconds
In this question we are being asked for time in Minutes and not in seconds. So let us convert 800 seconds into minutes.
1 second = 1/60 minute
800 seconds= 800 × 1/60 = 13.3 minutes.
