Answer:
Imani traveled faster because her distance surpassed Linda's distance after the fourth hour.
Step-by-step explanation:
1. Understand the slope:
Ok, so the slope basically tells us how fast Imani and Linda traveled, so if we solve for the slope we know how fast Imani and Linda traveled.
2. Find Linda's slope:
- Take any two points: (0,10) and (1, 65).
Slope = (<u>y1 - y2)/(x1 - x2)</u>
<u> </u> = (65-10)/(1-0)
= 55
Since the slope is 55, we know her speed is 55 miles per hour.
2. Find Imani's slope:
- Take any two points: (0,0) and (1, 60).
Slope = (<u>y1 - y2)/(x1 - x2)</u>
<u> </u> = (60-0)/(1-0)
= 60
Since the slope is 60, we know her speed is 60 miles per hour.
3. Compare: Since 60>55, we know Imani traveled faster. If we look at options, we can see there's only one answer which shows that Imani traveled faster, so that must be the answer.
