# Easy Time, Speed & Distance Solved QuestionAptitude Discussion

 Q. A hare sees a dog 200m away from her and scuds off in opposite direction at a speed of 24 km/hr. Two minutes later the dog perceives her and gives chase at a speed of 32 km/hr. How soon will the dog overtake the hare, and what distance from the spot from where the hare took flight?
 ✖ A. 8 min, 2 km ✖ B. 7.5 min, 2 km ✔ C. 7.5 min, 3 km ✖ D. 7.5 min, 2.5 km

Solution:
Option(C) is correct

Distance covered by hare in 2 min = $\dfrac{24}{60}\times 2=800$ m

Now to overtake the hare dog has to cover a distance of $(800+200)=1000$ m with the relative speed of $(32-24)=8$ km/hr

Time = $\dfrac{1}{8}$ hr

Now distance travelled by hare in $\dfrac{1}{8}$ hr

$=\dfrac{1}{8}\times 24=3$km
