excluding stoppages , the speed of a bus is 62 kmph and including stoppages , it is 56 kmph . for how many minutes does the bus stop per hour ?
"d 10 min due to stoppages , it covers 6 km less . time taken to cover 6 km = ( 6 / 62 x 60 ) min = 6 min"
multiply(const_60, divide(subtract(62, 56), 62))
