Final answer:
Caspar skied down a 1,375-foot hill in 55 seconds at a speed of 25 feet per second, making option 3 the correct answer.The correct answer is 3.
Step-by-step explanation:
The correct answer is 3.
First, we need to convert the distance Caspar skied (1,375 feet) and the time it took him (55 seconds) into units that are easier to work with. Since we're dealing with speed, we want to convert distance and time into feet per second (ft/s).
To convert feet to meters, we know that there are 3.281 feet in one meter. So, 1 foot is approximately 0.3048 meters. To convert seconds to minutes and seconds, we know that there are 60 seconds in one minute. So, 1 second is approximately 0.0167 minutes.
Here's how we can calculate Caspar's speed:
1) Convert distance and time:
- 1,375 feet is approximately 420 meters (since 1 foot is approximately 0.3048 meters)
- 55 seconds is approximately 0.917 minutes (since 1 second is approximately 0.0167 minutes)
2) Calculate speed:
- Speed = Distance / Time
- Speed = 420 meters / 0.917 minutes (approximately)
- Speed = Approximately 462 meters per minute (approximately)
- Speed = Approximately 2,833 feet per minute (approximately)
- Speed = Approximately 2,833 feet per minute / 60 seconds per minute (approximately)
- Speed = Approximately 47.22 feet per second (approximately)
So, Caspar skied down the hill at approximately 47.22 feet per second (ft/s). However, since we're asked to write it as a whole number, we can just round it up to:
Caspar skied down the hill at approximately 47 feet per second (ft/s).
