Find the optimal time τ for foraging in preparation for the journey, expressed in terms of theparameters a, b and d

A race consists of three tracks – an uphill track from A to B, a downhill track from B to C, and an uphill track from C to D. The lengths of the three tracks are equal. Anil travelled from A to D covering the uphill and downhill tracks at 6 km/hr and 9 km/hr respectively. He took hours to reach D. Find the time that he would take to return from D to A (in hrs).2

Select the correct answerIf Abhi travels a certain distance at 6 km/hr, he reaches his destination 12 minutes early, but if he travels at 4 km/hr, he reaches his destination 10 minutes late. The speed (in km/hr) at which he should travel to reach his destination on time is?

If a train runs at 40 km/h, it reaches its destination late by 11 min, but if it runs at 50 km/h, it is late by 5 min only.
