Question

An elevator ascends at a rate of 29.6 feet per second. If a building is 1,450 feet tall, about how long would it take for the elevator to travel from the ground floor to the roof

Answer 1

1,450/29.6= 48.986 seconds
It would take 49 seconds for the elevator to travel from the ground floor to the roof.

Answer 2

49 seconds.

Explanation:

We have been given that an elevator ascends at a rate of 29.6 feet per second. A building is 1,450 feet tall. We are asked to find the time it will take for the elevator to travel from the ground floor to the roof.

To find the time taken by elevator to reach the top of the building, we will use rate formula.

`\text{Time}=\frac{\text{Distance}}{\text{Rate}}`

`\text{Time}=\frac{\text{1450 ft}}{\frac{\text{29.6 feet}}{\text{second}}}`

`\text{Time}=\frac{\text{1450 ft}}{\text{29.6 feet}}*\text{second}`

`\text{Time}=48.986486*\text{second}`

`\text{Time}\approx 49\text{ seconds}`

Therefore, it will take approximately 49 seconds for the elevator to travel from the ground floor to the roof.
