9514 1404 393
Answer:
54 3/5 mi/h
Step-by-step explanation:
To find miles per hour, divide miles by hours.
(18 1/5 mi)/(1/3 h) = (18 1/5)(3/1) mi/h = 54 3/5 mi/h
0 hours-
Jordan: 10
Jake: 15

They will have made the same amount of money after they have completed 2 hours of work each.
--------------------------
Another easy way to find the answer is to put the two into expressions and combine into an equation:
Jordan: 9x+10
Jake: 6.5x+15
Put into one equation:
9x+10=6.5x+15
Solve:
9x+10=6.5x+15
Step 1) Subtract 6.5x from both sides:
2.5x+10=15
Step 2) Subtract 10 from both sides:
2.5x=5
Step 3) Divide by 2.5 on both sides:
x=2
Step 4) Your answer:
You get the same 2 (hours)
If you need the value (Like how much money they made) then just plug in your x value to both expressions.
9x+10=
18+10=
28
6.5x+15=
13+15=
28
