The ratio between the speeds of two buses is 5 : 3. If the 1st bus runs 400 km in 8 h, then find the speed of the 2nd bus.?
Correct Answer: 30 km/h
Explanation:
Let speed of 1st bus = 5k
and speed of 2nd bus = 3k
According to the question,
5k = 400/8 = 50
∴ k = 50/5 = 10
∴ Speed of 2nd bus = 3k = 3 x 10 = 30 km/h
