Question

A swimmer swam 600 yards in 52 seconds. How many feet per second did he swim?

Answer 1

First you want to convert the yards to feet. There are 3 feet in 1 yard. So you will multiply the number of yards by 3. 

 

600 yards x 3 feet = 1800 feet. 

 

You want the number of feet per second that the swimmer swam. You will determine this by dividing the total number of feet swam by the total number of seconds. 

 

1800 feet/52 seconds = 34.6 feet/second.

 

Using significant figures, it would be 35 feet/second.
