Aladder that is 13 feet long is 5 feet from the base of a wall. how far up the wall does the ladder? reach?

This makes a triangle with one side of 13 one of 5 and the other x. In this case the x is 12 because 13,12,5 triangles are a special case, a Pythagorean triple. 5^2+12^2=13^2 
25+144=169
169=169

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.
