Biker B can cycle faster, 12 mph

Biker A can cycle faster, 12 mph

Biker B can cycle faster, 15 mph

Biker A can cycle faster, 15 mph

Answer 1

To determine which biker can cycle faster, we need to calculate their speeds in miles per hour (mph).

For Biker A:

• From the provided data points:
  • (1, 15): 1 hour = 15 miles → speed = 15 mph
  • (2, 30): 2 hours = 30 miles → speed = 15 mph
  • (3, 45): 3 hours = 45 miles → speed = 15 mph

Biker A's speed is consistently 15 mph.

For Biker B:

• From the provided data points:
  • (1, 12): 1 hour = 12 miles → speed = 12 mph
  • (2, 24): 2 hours = 24 miles → speed = 12 mph
  • (3, 36): 3 hours = 36 miles → speed = 12 mph

Biker B's speed is consistently 12 mph.

Comparing the two speeds:

• Biker A: 15 mph
• Biker B: 12 mph

Thus, Biker A can cycle faster at 15 mph.

The correct answer is: Biker A can cycle faster, 15 mph.
