Answer:
Let d = the one-way trip
Write a time equation: time = dist/speed
time out + time back = 4.5 hrs
d/80 + d/100 = 4.5
Multiply by 400 to clear the denominators
400*d/80 + 400*d/100 = 400(4.5)
Cancel the denominators
5d + 4d = 1800
d = 1800/9
d = 200 miles max distance
Devide the numerator by the denominator, and look for the repeating numbers
17 divided by 60 = 0.283333333 = repeating
25 divided by 60 = 0.4166666667 = terminating at the 7
31 divided by 44 = 0.7045454545= repeating i think? sorry i cant remember if double numbers repeating like this is the same
54 divided by 72= 0.75 = terminating
The answer is, x=11
hope this helps!
I'm pretty sure that you multiply 10x by 6. Since it is length by width those are the length and the width.
Glad I could help!
