How Much Distance Covered by the Boy? If
Answer: (2) 400 m
Let the speed of boy = X & the speed of car = Y
Time = distance/speed
= 10/X = 25/Y
X/ Y = 10/25
1 km = 1000 m
Distance covered by boy = time taken by car for travelling 1000 m x speed of X
time taken by Y = 1000/Y
Then, distance covered by boy = 1000/X x Y
1000 x 10/25
= 400 m.
Hence, the answer is (2) 400 m.
