Answer 1

To determine which biker rides at a greater speed, we need to find out Kevin's speed. We can do this by selecting one of the points from the table and using the formula:

Speed = Distance / Time

Let's use the point (2, 20), which means Kevin rides 20 miles in 2 hours.

Kevin's Speed = Distance / Time = 20 miles / 2 hours = 10 miles per hour.

Now we can compare Jeremy and Kevin's speeds:

Jeremy's speed: 15 miles per hour
Kevin's speed: 10 miles per hour

Since 15 miles per hour > 10 miles per hour, Jeremy rides at a greater speed.
