Solve the problem.Ken is 6 feet tall and is walking away from a streetlight. The streetlight has its light bulb 14 feet above the ground, and Ken is walking at the rate of 1.5 feet per second. Find a function, d(t), which gives the distance Ken is from the streetlight in terms of time. Find a function, 
, which gives the length of Ken's shadow in terms of d. Then find 
.
A. (S ? d)(t) = 2.54t B. (S ? d)(t) = 0.83t C. (S ? d)(t) = 1.13t D. (S ? d)(t) = 1.43t
