It rotates 360 degrees and 180 half way in a circular motion
1/4, 2/5, 0.5, 0.75
1/4 is 0.25
2/5 is 0.40
Then order from least to greatest.
<span>t+u = 10
10u+t= 10t+u-54
Rearrange:
t+u=10
9t-9u=54
Simplify:
1st; t+u=10
2nd: t-u=6
Add 1st and 2nd and solve for t,as follows:
2t = 16
t = 8
Substitute in t+u=10 to solve for u:
8+u=10
u = 2
Original Number = 82</span>
They traveled approximately 165 miles.The speed is not constant so it is not the exact number.
