How long will it take for a jeep to travel a distance of 250 km? (M.B.A., 2005) I. The relative speed of the jeep with respect to the car moving in the same direction at 40 kmph is 50 kmph. II. The car started at 3.00 a.m. in the morning.
Answer
SELF-PRACTICE — the source book printed no answer.
Nothing is invented here, so this question has no answer on record.
Explanation
I. Speed of the jeep $=(40+50)\mathrm{kmph}=90\mathrm{kmph}$. $\therefore$ Required time $=\left(\frac{250}{90}\right)\mathrm{hrs}=\frac{25}{9}\mathrm{hrs}=2\frac{7}{9}\mathrm{hrs}$. So, I alone gives the answer while II alone does not. $\therefore$ Correct answer is (a).
