A children's roller coaster travels along 3300 feet of track at a rate of 15 miles per hour how many seconds does the take to travel this length of track

150 seconds

Step-by-step explanation:

To carry out this exercise we first have to know the equivalence between miles-feet and hours-seconds.

1 mile = 5280 feet

1 hour = 3600 seconds

now with that information we can pass miles per hour to feet per second

15 mi/h = 15 * 5280 f / 3600 s

15 mi/h = 22 ft/s

we know that the speed is 22 ft/s, and the distance is 3300 ft, using the formula v = d / t

v = velocity = 22 ft/s

d = distance = 3300 ft

t = time = ?

v = d / t

t = d / v

t = 3300 ft / 22 ft/s

t = 150 s

it will take 150 seconds to travel the length of track

the answer is b.)

< 1=< 2

from the figure we get,

the x axis shows   the months and,

the y-axis shows the number of satisfied customer.

each line or each cell in upward direction (y-axis) shows 500.

the appropriate scale for the y - axis is: -

a = 2000 customers

b = 4000 customers

c = 6000 customers

d = 8000 customers

e = 10000 customers

f = 12000 customers

g = 14000 customers
