I assume you are asking how much time has passed
now, we can set up a proportion with this:
let x = time(in hours)
\frac{120miles}{50miles} = \frac{x}{1 hour}
we cross multiply to get:
50x=120
divide both sides by 50 to get:
x= \frac{120}{50} =2.4= \frac{12}{5}=2 \frac{2}{5} hours

sladkih [1.3K]

Answer:

Marta's rope is 94"

Step-by-step explanation:

D = dilberts rope length

M = marta's rope length

Marta's jump rope is 10" shorter than four times the length of Dilbert's rope

M = 4D-10

both their ropes laid together end to end and measured 120" long

M+D = 120

Substitute 4D-10 for M in the second equation

4D-10 + D = 120

Combine like terms

5D-10=120

Add 10 to each side

5D-10+10 =120+10

5D =130

Divide by 5

5D/5 = 130/5

D =26

Now we need to find M

M+D = 120

M +26 = 120

Subtract 26 from each side

M = 120-26

M = 94
