Answer:
The speed of the elevator in miles per hour is
Step-by-step explanation:
We are given
The elevator in the Washington Monument takes 75 seconds to travel 500 feet to the top floor
so,
total distance is 500 ft
Firstly, we will change feet to miles
we know that
1 mile = 5280 feet
so,
we can multiply both sides by 500
so,
total time is 75 seconds
now, we can change seconds into hours
we know that
1 hour =3600 seconds
so,
we can multiply both sides by 75
we know that
speed = distance / time
so,
now, we can plug values
now, we can simplify it
So,
The speed of the elevator in miles per hour is

Answer:
$866.13
Step-by-step explanation:
to get an average, you add up all the factors then divide them by how many there are. I added 500 12 times to 1250 12 times to 1150 3 times and 600 4 times.
aka (500*12)+(1250*12)+1150+1150+1150+600+600+600
then i divided by 31 because 12+12+3+4=31. giving the average $866.13.
