Write an expression representing the total distance he should bike over the four days in terms of how far he bikes on the first day, x. Do not combine like terms.

Answer: 24x^3√(5x) - 4x^3√(10x)mark me brainliest

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.
