# Easy Time, Speed & Distance Solved QuestionAptitude Discussion

 Q. Jay started cycling along the boundaries of a square field from corner point $A$. After half an hour he reached the corner point $C$, diagonally opposite to $A$. If his speed was 8 km/hr, the area of the filed in square km is:
 ✖ A. 64 ✖ B. 16 ✖ C. 9 ✔ D. 4

Solution:
Option(D) is correct

Distance covered by Jay in $\dfrac{1}{2}$ hr = 4 km

Therefore, side of the square = $\dfrac{4}{2}=2$ km

Hence, Area = $2×2$ = 4 square km
