Find the ratio of speed of truck to train if truck covers 550m in 1 minute and train covers 33 km in 45 min.	Answers:
A) 3:9 B) 8 C) 3:2 D) 3:4 E) 3:1
Explanation:   Using the formula, speed=distance/time   Speed of truck = 550/60 m/s   Speed of train= 33000/(45*60) m/s   Ratio of speed of truck to train= (550/60 ) / [33000/(45*60)]   =3:4   Hence, the ratio is 3:4   ANSWER: 3:4
