Question

Kevin gets on an elevator in a skyscraper. The elevator starts to move at a rate of -15ft/s. After 4 seconds on the elevator, Kevin is 260 ft from the ground floor of the building. Fill in the Blank: How many feet was Kevin above the ground when he got on the elevator? _________feet. (YOUR ANSWER SHOULD BE A NUMBER ONLY.)

Answer 1

Let h = Kevin's starting height when he got on the elevator. Since distance = rate x time, and the rate = -15 f/s and time = 4 seconds, so:

h - distance x rate = 260

h - 15·4 = 260

h - 60 = 260

Solve for h. The units are feet.
