Question

Marta’s jump rope is 25 inches shorter than one and half times the length of Dilbert’s rope. If both their ropes laid together end to end measure 221 inches long, how long is Marta’s jump rope?

Answer 1

Answer:

Step-by-step explanation:

Let Dilbert's rope=x inches

then mantra's rope=(1+1/2)x-25=3/2x-25

Now x+3/2x-25=221

5/2x=246

x=246*2/5=98.4 inch

mantra's rope length=98.4*3/2-25=122.6 inch

"Happy rope jump"
