not able to understand this question Ajay was traveling on NH-10 on his bike when he witnessed a road accident in which Minu and Sonu were seriously injured. Ajay needs to make sure that both of them reach the Highway hospital, which is 180 km, at the earliest (one person at a time). Even after being injured Minu and Sonu can walk at a speed of 4kmph while Ajay’s motorcycle can travel at 36kmph. What is the earliest time at which all three can reach the hospital if Ajay witnessed the accident at 11:00am?
