Question 1042630
"Artie walked up the tree at a rate of 1.5 feet per minute", so r = 1.5
The tree is 108 ft tall, so d = 108


D = r*t
108 = 1.5*t
108/1.5 = (1.5*t)/1.5
72 = t
t = 72


It took Artie 72 minutes to go up the tree


----------------------------------------------------------------------------


"Artie walked...down the tree at a rate of 2.25 feet per minute", so r = 2.25
D = 108 is the distance from the top to the bottom of the tree


D = r*t
108 = 2.25*t
108/2.25 = (2.25*t)/2.25
48 = t
t = 48


It took Artie 48 minutes to go down the tree

In total, the ant traveled for 72+48 = 120 minutes
