Two cities are 210 km apart. A train traveled this distance in 42 3 hours and then made the return trip at a speed of 502 5 km/h. How many times greater (or less) was the train’s speed on the return trip?

Respuesta :

5 and 2/5km/hr

Explanation
The speed for the first journey is 210km/ 4 and 2/3 km/h
This gives 45km/hr
The difference is (50 2/5 - 45)km/hr
This gives 5 2/5km/hr
