Question

Cities A, B, and C are at a distance of 45 km, 50 km and 55 km respectively from Raghu's home. He observed that he can cover 2 km in 10 minutes on his cycle. If he has 4 hours time limit, which city he can reach on cycle if he travels at observed speed?

• A. A
• B. B
• C. C
• D. He cannot reach any city

Answer 1

The correct option is A

A

As he goes at same speed , $\frac{Distance}{Time}$ remains constant. So, they are in proportion.

$⟹\frac{2}{10}=\frac{x}{4\times 60}$

$⟹x=48km$.

Hence Raghu can reach city A in given time.
