Question

A truck covers a distance of $550$ metres in $1$ minute whereas a bus covers a distance of $33$ km in $45$ minutes. What is the ratio of their speeds?

• A. $3:4$
• B. $2:7$
  
• C. $5:8$
  
• D. $3:8$
  

Answer 1

The correct option is A $3:4$

Required ratio = Speed of truck : Speed of bus= $\frac{550}{60}$ m/sec : $\frac{33\times 1000}{45\times 60}$ m/sec =$\frac{55}{6}$ m/sec : $\frac{110}{9}$ m/sec = $\frac{55}{6}\times \frac{9}{110}=\frac{3}{4}=3:4$
