Rate = 11/5 * 24 = 11/5 * 24 ft/day

Distance = 1/2 mile = 2,640 ft.

Time = distance/rate = (2,640)/(11/5 * 24) =

(2,640 * 5)/(11 * 24)= (240 * 11 * 5)/(11 * 24)

= 10 * 5 = 50

Answer choice E

Time required = \(\frac{5280}{2}*\frac{5}{11}*\frac{1}{24}\)

Time required = \(50\) , Answer must be (E)
