The ratio between the speeds of two cars is 5:8. If the first car covers 200 km in 2 hours, find the speed of the second car.
Answer & explanation
Correct answer: option 2
Speed of 1st car = S = \(\frac{D }{ T}\) = \(\frac{200 }{ 2}\) = 100 km/h
The ratio of speed of 2 cars = 5: 8
If the value of 5 is 100 then, the value of 8 is → \(\frac{100 }{5 }\) * 8
The speed of the second car is 20 * 8 = 160km/hr
