a bullock cart has to cover a distance of 80 km in 10 hrs. if it covers half of the journey in 3 / 5 th time. what should be its speed to cover the remaining distance in the time left.
divide(divide(80, const_2), subtract(10, multiply(divide(10, 5), 3)))
a 10 kmph time left = 10 - 3 / 5 * 10 = 4 hr 10 km / h speed = 40 km / 4 hr = 10 kmph
