Question

Excluding the stoppages, the speed of a bus is 64 km/hr and including the stoppage the speed of the bus is 48 km/hr. for how many minutes does the bus stop per hour?

Answer 1

$64 - 48 = 16$
$48 = 16 \div x \\ x = 16 \div 48 = 0.33$
this was because speed =distance÷time
multiply it by 60
that is 60×0.33=20min is approx ans
