17.Always. 4+8, 3+8 any etc. this isn't a solution and therefore no fixed number is present
18. False. 12-8=4 there is no other possible answers avaliable to this
Step-by-step explanation:
written down already . please put as brainliest
While going to the ice
skating rink,
Rosario drives a distance of 55 miles in = 1 hour
Then
While going to the
ice skating rink,
Rosario
drives a distance of
120 miles in = (1/55) * 120
<span> = 2.18 hours</span>
The number of miles
per hour Rosario averages while coming back home = x
Total up and down
time taken by Rosario = 2.75 hours
Then time taken by
Rosario to come
back
home from ice
skating rink = (2.75 – 2.18) hours
<span> =
0.57 hours</span>
Then we can write
the equation as
x = 120/0.57
miles/hour
<span>
= 210.53 miles/hour</span>
<span>So the average speed
of Rosario while coming back home from ice skating rink is 210.53 miles per
hour.</span>
