Final answer:
Jana biked 4 miles in the last 15 minutes, with a speed of 16 miles per hour converted to 0.2667 miles per minute for the calculation.
Step-by-step explanation:
To calculate the distance Jana biked in the last 15 minutes at a speed of 16 miles per hour, we need to convert the speed to miles per minute and then multiply by the number of minutes.
Firstly, we convert the speed from hours to minutes: 16 miles per hour
= 16 miles/60 minutes
= 0.2667 miles per minute.
Then, we calculate the distance covered in 15 minutes: Distance = Speed × Time
= 0.2667 miles/minute × 15 minutes
= 4 miles.
Therefore, Jana biked 4 miles in the last 15 minutes.
