A children's roller coaster ride travels along 3,300 feet of track at an average rate of 15 miles per hour. How many seconds does the ride take to travel this length of the track?

Time = 149.688 seconds

Step-by-step explanation:

First the conversation rate of ft to miles is

1 foot = 0.000189 mile

So 3300 feet = 3300*0.000189

= 0.6237

3300 feet = 0.6237 mile

So the roller coaster traveled 0.6237 mile.

But the speed of the roller coaster is 15 mile/hour

To calculate for time

Speed = distance/time

Time = distance/speed

Time = 0.6237/15

Time = 0.04158 hour

Converting to seconds , we multiply time by 3600

Time in seconds = 0.04158*3600

Time = 149.688 seconds

jk it's 20

step-by-step explanation:

really really sorry if i'm

-12 -5(x + 4) = 3x

-12 - 5x - 20 = 3x

-12 - 20 - 5x = 3x

-32 - 5x = 3x

    + 5x   + 5x

-32 = 8x

8         8

- 4= x
