Answer:Hope it will help.

Explanation:

Answer 2

Answer:

we know that circumference of circle is 2piR

radius is given R=105 meter

time 2 minutes change in second i.e 2×60=second

distance = circumference of circle

distance=2×3.14×105=659.73 meters

time= 120sec

we know that

distance =speed×time

speed=659.73/120= 5.49 meter per second
