Lainey is sliding down a water slide that is 376 feet long at a rate of 47 feet per second. How long will it take Lainey to travel from the top to the bottom of the slide?

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.

area of part 1:

a1=base*height/2=(8+2)*(8-2-2-1)/2=10*3/2=15 ft^2

area of part 2:

a2=length*width=(8+2)*1=10 ft2

area of part 3:

a3=length*width=8*2=16 ft2

total shaded area : a1+a2+a3=41 ft2

total area of the reactangle : a=16*8=128 ft2

total area of the nonshaded region : 128-41=87 ft2

-2

7 - 9 = -2

reversed:

-2 + 9 = 7
