Answer:
27/16
Step-by-step explanation:
1/2+3/4+7/16=...
8/16+12/16+7/16=27/16
Number = -14
(-14)+(-6)=-8
(-8)*(-3)=24
Distance = rate * time
trip there, 120 = 55 *t
t = 2 and 2/11 hours
trip back, 120 = r * (2.75 - 2.181818181) round trip time - time to get there
120 = r * .568181818181818
r = 211.2 miles per hour
thinking maybe you did not copy the problem accurately...thats pretty fast.
