Question

Lainey is sliding down a water slide that is 420 feet long at a rate of 42 feet per second. How long will it take Lainey to travel from the top to the bottom of the slide?

A) 378 seconds
B) -378 seconds
C) 10 seconds
D) -10 seconds

Answer 1

To find out how long it will take Lainey to travel down the slide, we divide the length of the slide (420 feet) by her speed (42 feet per second), which equals 10 seconds.

Step-by-step explanation:

The student question revolves around determining the time it would take for Lainey to slide down a water slide that is 420 feet long, at a speed of 42 feet per second. To calculate the time, we can use the formula:

Time = Distance / Speed

Substituting the given values into this formula:

Time = 420 feet / 42 feet per second = 10 seconds

Therefore, the correct answer to the question is C) 10 seconds.
