a man is walking at a speed of 10 km per hour . after every kilometre , he takes rest for 3 minutes . how much time will be take to cover a distance of 3 kilometres ?
"rest time = number of rest ã — time for each rest = 2 ã — 3 = 6 minutes total time to cover 3 km = ( 3 â  „ 10 ã — 60 ) minutes + 6 minutes = 24 minutes answer e"
add(multiply(divide(3, 10), speed(const_60, const_1)), multiply(const_4, 3))
