Final answer:
Using the formula Time = Distance ÷ Speed, and knowing Mrs. Szymanski travels 5 miles at 20 mph, the time it takes her to reach the gas station is 0.25 hours, or 15 minutes.
Step-by-step explanation:
To calculate the time it takes Mrs. Szymanski to get to the gas station, we can use the formula:
Time = Distance ÷ Speed.
In this case, Mrs. Szymanski travels a distance of 5 miles at a speed of 20 miles per hour (mph). Thus, the time it would take her to reach the gas station is calculated as follows:
Time = 5 miles ÷ 20 mph = 0.25 hours.
To convert this into minutes, we multiply by 60 (since there are 60 minutes in an hour):
0.25 hours × 60 minutes/hour = 15 minutes.
Therefore, it will take Mrs. Szymanski 15 minutes to get to the gas station.
