1. A truck covers a distance of 550 metres in 1 minute where as a bus covers a distance of 33 kms in 45 minutes. The ratio of their speeds is :
- A. 3 : 4
- B. 3 : 4
- C. 3 : 4
- D. 3 : 4
Answer: Option A
Explanation:
In the case of truck
S = 550m/60 = 9.166 = 9 m/sec
In the case of Bus
S = ( 33×1000)m /( 45×60)sec = 12 m/sec
So the speed ratio of truck : Bus = 9 : 12 = 3 : 4
