Answer 1

Step-by-step explanation:

20 foot is 240 inches

squirrelmoves 3 inch forward and 2 inch backward in 1 min after that he is 1 inch away from an initial position

x= 3-2=1m in 1 min

after 237min he will 237 inch away from an initial position

He moves further 3inch forward then and reach top which is 240 inch away from the initial position.

total time T=237min+ 12*3 sec=237 min 36 sec
