Final answer:
To calculate the distance Jack can jog in 3 minutes, first find his speed per minute and then multiply by 3. Jack can jog 21 feet per minute, so in 3 minutes, he can jog 63 feet.
Step-by-step explanation:
Calculating Running Distance
First, we will convert Jack's jogging rate from feet per 10 seconds to feet per minute. Since there are 60 seconds in one minute, we have six 10-second intervals in one minute. So, we multiply 3 ½ feet by 6 to get the distance Jack can jog in one minute:
3 ½ feet/10 seconds * 6 = 21 feet/minute
Next, to find out how many feet he can run in 3 minutes, we simply multiply his rate by 3:
21 feet/minute * 3 minutes = 63 feet
Therefore, Jack can jog 63 feet in 3 minutes at his current rate.
