Jen rode her bike

(1/5 mi) / 5min = 1/25 mi/min

this is wrong

(1/5 mi) / 5 min = 1/25 mi/min this is right for sure because i did it and i got it right

To calculate Jen's speed, we need to use the formula:

Speed = Distance/Time

First, we need to find the distance Jen traveled. The question states that Jen rode "1/5 of a mile" to her friend's house.

Next, we need to find the time it took Jen to travel the distance. The question states that it took her "5 minutes" to get there.

Now we can plug the values into the formula:

Speed = (1/5 mile)/(5 minutes)

To simplify this, we can convert the time to hours since speed is usually measured in miles per hour. There are 60 minutes in an hour, so:

Speed = (1/5 mile)/(5/60 hours)

Simplifying further:

Speed = (1/5 mile) * (60/5 hours)

Speed = 12 miles/hour

Therefore, Jen's speed was 12 miles per hour.
