The speed is 64 miles per hour
Step-by-step explanation:
Lets define speed first.
"Speed is the distance per unit time"
Speed is denoted by s.
Given
Distance = d = 160 miles
Time = t = 2.5 hours

Hence,
The speed is 64 miles per hour

Answer:
The answer would be 5.03x10^-3 ^-^
Step-by-step explanation:
I think there is infinite amount of solutions
L=17.49635531
W=5.715476066
100 = L X W
L = 2+ 3W
Insert the L equation into the 1st equation, 2+ 3W x W = 100
<span>2+ 3W x W = 100
</span>-2 -2
3W X W = 98
3W^2 = 98
Divide both sides by 3
W^2 = 32.66
Square root both sides
now you have the Width, plug the width into the L X W = 100 equation, then divide 100 by the width, and now you have the length.
(this is what I think) Every 40 miles,the car uses 1 gallon,Try doing 750/40=18.75 if not,try figuring out how much gas he uses in 18.75 gallons.
