1) A car is traveling at a rate of 70 miles per hour. what is this speed in feet per minute.
2) Nina can braid 28 inches of rope in 1 hour. What is her speed in feet per hour?
I am studying but I don't understand these questions. I have test tomorrow. Thank you.
1 mile = 5,280 feet
(70 * 5,280) / 60 = _______ ft/minute
28 inches = 2 1/3 feet
Don't worry, I'm here to help you understand these questions! Let's break it down step by step.
1) To find the speed of the car in feet per minute, we need to convert from miles per hour to feet per minute. Here's how you can do it:
- First, convert 70 miles to feet. Since 1 mile is equal to 5,280 feet, you can multiply 70 by 5,280 to get the distance in feet.
70 miles * 5,280 feet/mile = 369,600 feet
- Now, divide the distance in feet by the time, which is 1 hour, to get the speed in feet per hour.
369,600 feet / 60 minutes = 6,160 feet per minute
So, the car is traveling at a speed of 6,160 feet per minute.
2) Similarly, to find the speed of Nina braiding rope in feet per hour, we'll need to convert inches to feet and then divide by time.
- You're given that Nina can braid 28 inches of rope in 1 hour. To convert inches to feet, divide 28 by 12 (since there are 12 inches in a foot).
28 inches / 12 inches/foot = 2.333 feet
- Now, divide the distance in feet by the time, which is 1 hour, to get the speed in feet per hour.
2.333 feet / 1 hour = 2.333 feet per hour
So, Nina's speed in braiding rope is 2.333 feet per hour.
Make sure to write down these steps and formulas so you can refer to them during your test. Good luck with your studying and your test! If you have any more questions, feel free to ask.
