Question

An elevator goes up a multi storey building at a rate of 6 m/min if it starts from 20 m above the ground how long will it take to reach 320 m

Answer 1

the elevator has to travel 320 -20= 300m
it travels 6m in = 1min
it travels 1m in = 1/6 min
it travels 300m in = 1/6 *300
it travels 300m in = 50 minutes
