Speed ratio of two cars: 5 ∶ 7
Distance covered by the first car: 200 km
Time taken by the first car: 4 hours
Concept:
Ratio of speeds and calculation of speed.
Calculation:
⇒ The speed of the first car = 200 km / 4 hours = 50 km/h.
⇒ If speed ratio is 5 ∶ 7, then the speed of second car is 7/5 × speed of first car.
⇒ Speed of second car = 7/5 × 50 km/h = 70 km/h.
Therefore, the speed of the second car is 70 km/h.
