Question

The frog is climbing out of a well that is 50 Feet deep. The frog can climb 7 feet per hour but then a rest for an hour and it slips back 3 feet while resting. How long will it take for the frog to get out of the well?

Answer 1

Answer: 12 Hours after 48 Leaps

Step-by-step explanation: A simple way of looking at this problem is like this:

7 (-3) = 4 | 4 x 1

7 (-3) = 8 | 4 x 2

7 (-3) = 12 | 4 x 3

7 (-3) = 16 | 4 x 4

7 (-3) = 20 | 4 x 5

7 (-3) = 24 | 4 x 6

7 (-3) = 28 | 4 x 7

7 (-3) = 32 | 4 x 8

7 (-3) = 36 | 4 x 9

7 (-3) = 40 | 4 x 10

7 (-3) = 44 | 4 x 11

7 (-3) = 48 | 4 x 12

Each leap back will become a multiple of four. Most of the time it will always be a number that’s close to the total number but not quite the total number itself. That will be your answer.

Answer 2

7-3=4 feet per hour

50 : 4 = 12,5  hour
