Two men P and Q start together from place A at 3 km/h and 3.75 km/h respectively for place B. Q reaches half an hour before P. What is the distance that each one has covered?
Answer & explanation
Correct answer: option 3
Let the distance = a
According to the question,
= \(\frac{a}{3}\) - \(\frac{a}{3.75}\) = \(\frac{1}{2}\)
= 2.5a - 2a = 3.75
= .5a = 3.75
a = 7.5 km
