Eli traveled a total of 8.6 miles. He went to the library and back. 3.75 + 3.75. and he also added and extra 1 1/10 mile. so, 3.75 x 2 = 7.5, 7.5 + 1 1/10 = 8.6. Hope that helped!
M=-3.5+2t, R=-3t when they meet M=R so
-3.5+2t=-3t
-3.5+5t=0
5t=3.5
t=0.7 hrs (42 minutes)
Stack them all up in a row:
0.06
0.16
0.60
0.66
Now order them from least to greatest by each place
0.06, 0.16, 0.60, 0.66
(LOL, you TYPED them least to greatest!)
