In a trip, Ram can cover a distance of 200 km in 10 hours. First he started by Bike at the speed of 15 km/h. After that his bike broken down and cover the remaining distance by his friend's car at the speed of 25 km/h. Ratio between the distance covered by bike and car is ____________.
Answer & explanation
Correct answer: option 1
Distance = Speed × Time
Speed = \(\frac{Distance}{Time}\)
Time of journey = 10 hours
Let Distance covered by Speed 15 km/h = D km
& Distance covered by Speed 25 km/h = ( 200 - D) km
According to question ,
\(\frac{D}{15}\) + \(\frac{200 - D}{25}\) = 10
2D + 600 = 750
2D = 150
D = 75 km
& (200 - D) = 200 - 75 = 125 km
So , Ratio of distance covered by Byke and Car is
= 75 : 125
= 3 : 5
