Answer:
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
Thank you

Most tracks are 400 meters around, as measured in Lane 1; that's just a bit less than one-quarter of a mile. Here are some other measurements that it's helpful to know: 100 meters: the length of one straightaway. 800 meters: roughly ½ mile or 2 laps around the track
good luck, hope this helped
