in a kilometer race , a beats b by 50 meters or 10 seconds . what time does a take to complete the race ?
"explanation : time taken by b run 1000 meters = ( 1000 * 10 ) / 50 = 200 sec . time taken by a = 200 - 10 = 190 sec . answer b"
subtract(divide(multiply(const_1, const_1000), divide(50, 10)), 10)
