Question

A man is walking down a very long flight of

steps in a stairwell. He begins at 136 feet

above ground level. He walks down with a

steady rate such that he gets closer to the

ground floor at a rate of 2.8 feet per second.

The man is going to exit the stairwell at the

4th floor, which is the height of 42 feet above

ground level. Let t be equal to the number of

seconds it takes for him to get to the 4th floor.

Set up and solve the equation to find the value

of t. Round your answer to the nearest tenth

of a second.

Answer:33.6 seconds

Step-by-step explanation:if he begins at 136 feet and wants to go to 42 feet, the distance is 94 feet

d = 94

r = 2.8

d = rt; solving this formula for ‘t’:

t = d/r

t = 94/2.8

t = 33.6 seconds
