Answer 2

Given; The ratio between the speeds of two trains is 6:9. My first car covers 180 km in 3 hours

To Find; Speed of second train

Solution ; Ratio of speed of trains = 6:9

first train covers distance = 180 km

Time taken by first train = 3 hrs

Speed of first train = Distance / Time

=180 /3

= 60 km / h

Since the ratio is 6:9 So the speed of first train is 6x so the value of x is 10

According to this speed of seconds train is 90 km/h

Hence the speed of second train is 90 km/h
