Answer:
150 seconds
Step-by-step explanation:
Remember that
[tex]1\ mile=5,280\ feet[/tex]
To convert miles to feet multiply by 5,280
[tex]1\ hour=3,600\ seconds[/tex]
To convert hours to seconds, multiply by 3,600
step 1
Convert the average rate of miles per hour to feet per second
[tex]15\frac{mi}{h}=15(\frac{5,280}{3,600})=22\frac{ft}{sec}[/tex]
step 2
Find out how many seconds does the ride take to travel this length of track
we know that
The length of the track is 3,300 ft
so
Divide the total length of the track by the speed
[tex]\frac{3,300}{22}= 150\ sec[/tex]
