To determine which biker can cycle faster, we can compare their average speeds based on the distance traveled per hour.
From the data for Biker A:
- At 1 hour: 15 miles
- At 2 hours: 30 miles
- At 3 hours: 45 miles
The speed of Biker A can be calculated as follows:
- From the graph, Biker A travels 15 miles in the first hour, which means an average speed of 15 mph.
From the data for Biker B:
- At 1 hour: 12 miles
- At 2 hours: 24 miles
- At 3 hours: 36 miles
The speed of Biker B can be calculated as follows:
- From the table, Biker B travels 12 miles in the first hour, which means an average speed of 12 mph.
Now comparing the two:
- Biker A: 15 mph
- Biker B: 12 mph
Thus, Biker A can cycle faster at 15 mph.
The correct response is: Biker A can cycle faster, 15 mph.
