A car travelling at an average speed of 100km/h covers a certain distance in 3 hours 20 minutes . At what constant speed must the car travel to cover the same distance in 2 hours and 40 minutes ?
Step-by-step explanation: 100 (kph) multiplied by 3.33 (3 hrs 20mins) = 333 Kilometers. Now divide 333 by 2.66 (2 hrs 40 mins) and you will get 125.2 Kph.
