Question

You travel $\frac{5}{2}$ km in 4 minutes to reach a milestone. How far will you be from the milestone in 4 minutes if you travel at the same speed?

• A. $\frac{3}{2}$ km
• B. $\frac{5}{2}$ km
• C. 2 km
• D. $\frac{7}{2}$ km

Answer 1

The correct option is B $\frac{5}{2}$ km

Distance traveled in 4 minutes from starting point P to milestone = $\frac{5}{2}$ km

Distance traveled in another 4 minutes at the same speed from the milestone = $\frac{5}{2}$ km
Hence, the final position is at +2 on the number line, i.e.,


Distance of destination from milestone = $\frac{5}{2}$ km

Therefore, option (b) is the correct answer.
