Q: There was a 2 kilometre race between a cheetah and an elephant. Soon after the start of the race, the cheetah took a huge lead. On realizing that even after taking a nap of ‘t’ min, he would beat the elephant by 13 min, he stooped under a tree and went to sleep. Meanwhile the elephant kept walking. When the cheetah woke up, he realized that he had slept for (14 + t) min, and immediately started running towards the target at a speed 1.5 times his original speed. The race eventually ended in a dead heat. If the ratio of the original speed of the cheetah to that of the elephant was 6 : 1 and the cheetah overstretched his nap by 7/6*t min, then how long (in minutes) did the elephant take to complete the race?
