7.4. Winnie-the-Pooh and Tigger are climbing two identical fir trees. Winnie-the-Pooh climbs up at half the speed of Tigger, but he descends three times faster than Tigger. Winnie-the-Pooh and Tigger started and finished at the same time. How many times faster does Tigger climb up than he descends?
Answer: one and a half times. Let the time it takes for the Tiger to climb up be $T$ minutes, and the time to climb down be $t$ minutes. Then, Winnie-the-Pooh takes $2 T$ minutes to climb up, and $-t / 3$ minutes to climb down. According to the condition, $T+t=$ $2 T+t / 3$, from which we get $t=1.5 T$. Comment. Only the answer -2 points.
