The equations that can be used to represent this situation are y = 13x and
y = 11x + 20.
Explanation:
Given that,
- Jenna travels at a speed = 13 miles per hour.
- Alex travels 20 miles from her home at a speed = 11 miles per hour.
To find the total distance traveled by Jenna :
where,
- y represents the total distance.
- x represents the number of hours.
- Speed of Jenna is 13 miles per hour.
Distance = Speed
Time
y = 13x
To find the total distance traveled by Alex :
where,
- y represents the total distance.
- x represents the number of hours.
- Speed of Alex is 11 miles per hour.
- Alex travels an additional 20 miles from her home to reach Jenna.
Distance = Speed
Time
y = 11x + 20
