Step-by-step explanation:
Given well is 70 ft deep.
Each step of the climb involves moving up at 7 ft/hr and then slips down 2 feet. Assuming the frog rests only once each hour, then the resultant progress made each hour,
= distance climbed - distance lost by slipping
= 7 - 2
= 5 ft / hr
Hence we can say that :
5 feet ---> takes 1 hour
1 foot ---> takes 1/5 hours
70 feet ---> takes (1/5) x 70= 14 hours
