The storm will take 142.19 sec to encircle the planets equator
The Equatorial radius is the distance between a planet's center and its surface. Therefore, planetary radius is a measure of a planet's size
Equatorial radius of mars = 3396.2 km
circumference = 2πr
= 2 3.14 3396.2
= 21328.14 km
distance travelled by the storm will be 21328.14 km
distance = speed * time
time = distance / speed
= 21328.14 / 150
= 142.19 sec
The storm will take 142.19 sec to encircle the planets equator
