Question 18 options: the length of a rectangle is four times its width. if the perimeter is at most 100 centimeters, what is the greatest possible value for the width?

2(4b+b)=100
5b=50
b=10

hence breadth is 10cm

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.
