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?
Answer & explanation
Correct answer: option 4
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
