To determine which biker can cycle faster, we need to calculate their speed in miles per hour (mph) based on the data provided.
For Biker A: From the graph:
- At 1 hour, Biker A traveled 15 miles.
- At 2 hours, Biker A traveled 30 miles.
- At 3 hours, Biker A traveled 45 miles.
Biker A's speed is constant:
- Speed = Distance / Time
- For 1 hour: Speed = 15 miles / 1 hour = 15 mph
- For 2 hours: Speed = 30 miles / 2 hours = 15 mph
- For 3 hours: Speed = 45 miles / 3 hours = 15 mph
Biker A cycles at a constant speed of 15 mph.
For Biker B: From the table:
- At 1 hour, Biker B traveled 12 miles.
- At 2 hours, Biker B traveled 24 miles.
- At 3 hours, Biker B traveled 36 miles.
Biker B's speed is also constant:
- For 1 hour: Speed = 12 miles / 1 hour = 12 mph
- For 2 hours: Speed = 24 miles / 2 hours = 12 mph
- For 3 hours: Speed = 36 miles / 3 hours = 12 mph
Biker B cycles at a constant speed of 12 mph.
Conclusion: Biker A can cycle faster at a speed of 15 mph, while Biker B cycles at 12 mph.
Therefore, the correct response is: Biker A can cycle faster, 15 mph.
