a wheel with diameter 40 cm makes 50 revolutions per minute. how long it take to cover a distance of 6.28 km?
Answered by Reiny
circumference = 40π cm
so in one minute would cover 50(40π) or 2000π cm

to cover 6.28 km or 628000 cm would take
628000/(2000π) minutes , or
99.949.... minutes, which is appr 1hr and 40 minutes
Answered by aaruhi
circumference = diameter * 3.14 = 125.6 cm
in one minute = 125.6 * 50 = 6280 cm or 0.0628
to cover 6.28 km = 6.28/0.0628 = 100m or 1 hour 40 minutes
