Julia the cat wants to climb a tree that is 73 ft high. Every day she climbs 11 feet, but then during the night she comes back down 7 feet. Assuming that Julia does not fall, how long will it take her to reach the top of the tree?

Sagot :

Answer:

  • 17 days

======================

Progress per day and night is:

  • 11 - 7 = 4 ft

Number of days to climb the tree less 11 ft:

  • (73 - 11)/4 =
  • 62/4 =
  • 15.5 =
  • 16 as whole number

Julia climbed in 16 days/nights:

  • 16 * 4 = 64 ft

One more day is required after this:

  • 16 + 1 = 17 days
