A triangle has side lengths measuring 3x cm, 7x cm, and hcm Which expression describes the possible values of h, in cm?
A) 4x< h< 10x
B) 10x C) h = 4x
D) h= 10x
It’s timed help pls :)

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.

Ithink it's the first one ( let me know if it right)
