Marta’s jump rope is 15 inches shorter than twice the length of Dilbert’s rope. If both their ropes laid together end to end measure 75 inches long, how long is Marta’s jump rope?

(1/x + 1)^2 + 6 (1/x + 1) +5

At a constant it will take one hour to travel 32 mi.at that speed it will take 1/2 hr to travel the remaining 16 mi.it will take 1+1/2 hr to travel the 48mi @ 32mph.so 1 hr = 60 min& 1/2 hr = 30 min1+1/2 hr = 90 min.there are 60s in each 90 × 60 = 3600 seconds.the real question seriously is he why are they driving so slow? ! lol.
