On the driver's arrival the photographer could set the right time on his watch. Can you tell me how? A wildlife photographer along with his driver was moving through an African jungle in his jeep. The jungle was dense and the road bumpy. The jeep accidentally hit a rock and the two men were thrown from their seats. The photographer's digital watch fell from his breast pocket and its battery popped out. Neither of them knew the correct time to re-synchronize the watch. Thus the photographer asked his driver to visit the nearest forest officer's home and inquire the time. The driver drove the jeep at a constant speed to the forest officer's place, asked him the time, rested there for 5 mins and drove back to the jungle at the same speed at which he had gone. On the driver's arrival the photographer could set the right time on his watch. Can you tell me how?

Assume that when the driver left, the photographer had turned his watch to a random time of 2:00 PM.

Let the total travel time of the driver be 2t, as he drove with the same speed on his forward and backward journey.

On the driver's return, the photographer's watch read (12 + 5/60 + 2t). From this, he could find out the value of t. The driver's journey from the time he quit the forest officer's home was T+t ( T being the time the driver noted while setting back for the jungle from the forest officer.) Since both the quantities are known the correct time could be determined.
