Final answer:
Jamar's running rate is 6/25 miles per minute, which is derived by dividing the distance he runs (3/5 mile) by the time it takes (2.5 minutes).
Step-by-step explanation:
Jamar can run 3/5 of a mile in 2 minutes and 30 seconds. To find his rate in miles per minute, we need to convert the 2 minutes and 30 seconds into minutes only. Since 1 minute is equal to 60 seconds, 30 seconds is equal to 1/2 a minute. Therefore, 2 minutes and 30 seconds is the same as 2.5 minutes.
To calculate Jamar's running rate, we divide the distance he can run by the time it takes. The calculation is as follows:
- Distance: 3/5 mile
- Time: 2.5 minutes
Rate = Distance / Time = (3/5 mile) / (2.5 minutes).
To simplify, we can multiply 3/5 by the reciprocal of 2.5 which is 2/5:
Rate = (3/5) * (2/5) = 6/25 miles per minute
