You can put this solution on YOUR website!
h = height of the coconut tree (in feet)
The time (in minutes) that Romy needs to climb to the top of the coconut tree is
h%2F10 .
The time (in minutes) that Romy needs to get down from the top of the coconut tree is
h%2F20
h%2F10%2Bh%2F20=3 --> 2h%2F20%2Bh%2F20%2B3 --> 3h%2F20=3 --> 3h=3%2A20 --> h=3%2A20%2F3 --> highlight%28h=20%29
The height of the coconut tree is highlight%2820%29 feet.
