how many minutes does aditya take to cover a distance of 400 m , if he runs at a speed of 20 km / hr
"explana ɵ on : we know that , time = distancespeedspeed = 20 km / hr = 20 ∗ 518 m / sec = 509 m / sec time = ( 400 ∗ 950 ) = 72 sec = 115 min answer : op ɵ on a"
divide(divide(400, multiply(20, const_0_2778)), const_60)
