A track covers a distance of 550 metres in 1 minute whereas a bus covers a distance of 33 kms in 45 minute. The ratio of their speeds is:

A. 4 : 3

B. 3 : 5

C. 3 : 4

D. 50 : 3

Answer: Option C

Solution(By Examveda Team)

Speed of track = 550 per minute.
Speed of bus = $$\frac{{33\,{\text{kms}}}}{{45}}$$   = $$\frac{{33000}}{{45}}$$  = 733.33 m/minute
Ratio of their speeds = $$\frac{{550}}{{733.33}}$$  = 3 : 4
