If a tire rotates at 150 revs/min when the truck is traveling 40km /h , what is the circumference of the tire?
.
Start by converting "revs/min" to "revs/hr"
150 revs/min * 60 min/hr = 9000 revs/hr
.
Since the truck travels 40 km in an hour, the circumference is:
Circumference = 40/9000 = 0.004444 km = 4.444 meters
