a wheel rotates 20 times every minute and moves 35 cm during each rotation . how many metres does the wheel move in one hour ?
number of times wheel moves in 1 hour = 20 * 60 = 1200 : . distance moves = ( 1200 * 35 ) cms = 42000 cms in metres = 420 metre answer : e
divide(multiply(multiply(20, const_60), 35), const_100)
