1. The posted speed limit on many US highways is 65 miles per hour. What is this speed in feet per second?
2. 3(3/4) yd is equal to how many inches?
To convert the speed from miles per hour to feet per second, you'll need to know the conversion factors. Here's how you can calculate it:
1. Start with the given speed limit: 65 miles per hour.
2. Convert miles to feet. There are 5,280 feet in one mile. Multiply 65 by 5,280:
65 miles/hour * 5,280 feet/mile = 343,200 feet/hour.
3. Convert hours to seconds. There are 3,600 seconds in one hour. Divide 343,200 by 3,600:
343,200 feet/hour รท 3,600 seconds/hour = 95.333 feet/second (rounded to three decimal places).
So, the speed limit of 65 miles per hour is approximately equivalent to 95.333 feet per second.
Now, let's move on to the second question:
To convert 3(3/4) yards to inches, you need to know the conversion factor for yards to inches. Here's how you can calculate it:
1. Start with the given measurement: 3(3/4) yards.
2. Convert yards to inches. There are 36 inches in one yard. Multiply 3(3/4) by 36:
3(3/4) yards * 36 inches/yard = 3 * 36 + (3/4) * 36 = 108 + 27 = 135 inches.
Therefore, 3(3/4) yards is equal to 135 inches.
