To determine which biker can travel faster, we need to calculate their speeds based on the information provided.
Biker A:
- Distance traveled in 1 hour = 15 miles
- Distance traveled in 2 hours = 30 miles
- Distance traveled in 3 hours = 45 miles
From this data, we can see that biker A's speed is consistent at:
- Speed = Distance ÷ Time = 15 miles ÷ 1 hour = 15 mph
Biker B:
- Distance traveled in 1 hour = 12 miles
- Distance traveled in 2 hours = 24 miles
- Distance traveled in 3 hours = 36 miles
From this data, we can see that biker B's speed is consistent at:
- Speed = Distance ÷ Time = 12 miles ÷ 1 hour = 12 mph
Now we can compare their speeds:
- Biker A: 15 mph
- Biker B: 12 mph
Based on this information:
- Biker A can cycle faster at 15 mph.
So the correct answer is: A: Biker A can cycle faster 15 mph.
