It takes the average high school swimmer 5 minutes and 30 seconds to swim 500 yards. How fast is the average swimmer moving in feet per second?

Round your answer to 3 significant figures and express your answer in decimal form.

Answer :

4.55 feet/second rounded to 3 significant figures is 4.56 feet/second, fast is an average swimmer moving in feet per second.

To calculate the speed of the swimmer in feet per second, we need to know how many feet are in 500 yards and then divide that by the time it takes the swimmer to swim 500 yards.

1 yard = 3 feet

So, 500 yards = 500 * 3 = 1500 feet

Time = 5 minutes and 30 seconds = 5 * 60 + 30 = 330 seconds

To find the speed in feet per second, we divide the distance by the time:

Speed = 1500 feet / 330 seconds = 4.55 feet/second

To round the answer to 3 significant figures, we look at the fourth digit after the decimal point, which is 5. Since it is greater than or equal to 5, we will round up the third digit after the decimal point from 5 to 6.

So, the speed of an average high school swimmer is 4.55 feet/second rounded to 3 significant figures is 4.56 feet/second.
