Answer:
30 feet
Explanation:
To solve this problem, we need to convert yards to feet and find the rate of running in feet per second. There are 3 feet in 1 yard, so 5 yards is equal to 15 feet. Keith runs 15 feet every 3 seconds, so his rate is 15/3 = 5 feet per second. To find how many feet he runs in 6 seconds, we multiply his rate by the time. So he runs:
5 * 6 = 30 feet
