a car travelling with 2 / 3 km of its actual speed covers 12 km in 2 hr 14 min 28 sec find the actual speed of the car ?
"time taken = 2 hr 14 min 28 sec = 823 / 50 hrs let the actual speed be x kmph then 2 / 3 x * 823 / 50 = 12 x = = 1.09 kmph answer ( c )"
divide(multiply(divide(12, add(2, divide(add(multiply(14, const_60), 28), const_3600))), 3), 2)
