Question

Two cities are 210 km apart. A train traveled this distance in 4 2/3 hours and then made the return trip at a speed of 50 2/5 km/h. How many times greater (or less) was the train’s speed on the return trip?

Answer 1

`4 (2)/(3)= (14)/(3)`

So,
`(210km)/( (14)/(3)hr )= 45km/h`


`50 (2)/(5) = (252)/(5)`


So,
`(252)/(5)/45= 1.12` times greater on the return trip.
