Solution

First, we need to calculate how long it takes Tenielle to walk to school.

The formula to calculate time is distance divided by speed.

So, walking time = distance / walking speed = 1.3 miles / 3 mph = 0.433 hours.

To convert hours into minutes, we multiply by 60.

So, walking time = 0.433 hours * 60 = 25.98 minutes.

Next, we calculate how long it would take her to bike to school.

Biking time = distance / biking speed = 1.3 miles / 6 mph = 0.217 hours.

Again, we convert hours into minutes by multiplying by 60.

So, biking time = 0.217 hours * 60 = 13.02 minutes.

Finally, we subtract the biking time from the walking time to find out how much time she would save.

Time saved = walking time - biking time = 25.98 minutes - 13.02 minutes = 12.96 minutes.

So, Tenielle could save approximately 12.96 minutes each morning by biking to school.

Rounded to two decimal places, this is 12.96 minutes.
