What do you need help with?
Answer:
8 seconds
Step-by-step explanation:
The length of the water slide is 376 feet and Lainey is sliding down at a rate of 47 feet per second. That is her speed.
Speed is given as distance divided by time or the time rate of displacement.
Therefore, time is:
Time = distance / speed
Therefore, the time it will take Lainey to get from the top to the bottom is:
Time = 376 / 47 = 8 seconds
It will take her 8 seconds to get from the top to the bottom.
To be divisible by both 7 and 8 a number must be a multiple of 56.
Multiples of 56 are just 56n. We wish to know the largest of three digit numbers that is a multiple of 56 then. So:
56n<1000
n<1000/56
n<17.86 and since n must be an integer n=17
Then the largest three digit multiple of 56 is:
56(17)=952
