When two pieces of rope are placed end to end, their combined length is 122 feet. when the two pieces
are placed side by side, one is 36 feet longer than the other. what is the length of the longest piece of
rope?

this may not be at all, but i use the same website you're using for school, and if i'm stuck doing one of these i try to look for it on the section.

multiplication is multiplication.   it might feel harder depending on what level of math you are in, but generally it will be the same old stuff, while implementing some new concepts and methods of solving work.

45.36 feet per second

step-by-step explanation:

tyrone travels 30 miles in 58.2 minutes.  

1 mile = 5280 feet; this means he travels

30(5280) = 158400 feet in 58.2 minutes.

1 minute = 60 seconds; this means he travels 158400 feet in

58.2(60) = 3492 seconds.

this gives us the unit rate of

158400/3492 = 45.36 feet per second.
