60=43× Speed of train
Speed of train =60×34
Speed of train =3240
Speed of train =80 km/h
The ratio of speeds of train and car is 16:15.
Train : Car =16:15
Car speedTrain speed=1516
Car speed80=1516
Car speed =80×1615
Car speed =5×15
Car speed =75 km/h
Distance covered by the car in 6 hours:
Distance =Speed×Time
Distance =75×6
Distance =450 km
Therefore, the distance covered by the car in 6 hours is 450 km.
