The ratio between the speeds of two cars is 5 : 7. If the first car runs 200 km in 4 hours, then what is the speed of second car?

65 kmph 60 kmph 50 kmph 70 kmph

70 kmph

Ratio of speed of two cars is   5 : 7 According to question , Speed = \(\frac{200}{4}\) = 50 km/h 5R = 50 km/h 1R = 10 km/h 7R = 70 km/h So , Speed of 2nd car is 70 km/h
