Answer 1

To determine which biker can cycle faster, we need to calculate the average speed for both bikers using the data provided.

Biker A:

• Assuming based on the responses that Biker A's average speed is 15 mph. (This seems to be information from the graph that we cannot see)

Biker B:

• From the table, we can calculate the average speed using the formula:

  \[ \text{Speed} = \frac{\text{Distance}}{\text{Time}} \]

For Biker B:

• After 1 hour: 12 miles -> 12 mph
• After 2 hours: 24 miles -> 12 mph
• After 3 hours: 36 miles -> 12 mph

Biker B's speed for all hours is 12 mph.

Conclusion: Biker A's average speed is 15 mph, while Biker B's average speed is 12 mph. Therefore, the correct response is:

Biker A can cycle faster, 15 mph.
