Question

Willy and Bill kept track of the distance each rode on his bike last week. Willy rode a total of 121.3 kilometers. Bill rode a total of 121.30 kilometers. Which statement is true? A. Bill rode a greater distance than Willy rode. B. Willy rode a greater distance than Bill rode. C. Willy and Bill rode an equal distance on their bikes.

Answer 1

The distances ridden by Willy and Bill are equal. To find which cyclist had the greatest average speed, calculate the speed for each and compare; the highest speed indicates the fastest cyclist which, in this case, is Cyclist 4.

Step-by-step explanation:

Regarding the initial question about Willy and Bill's bike rides, the correct statement is C. Willy and Bill rode an equal distance on their bikes. The numbers 121.3 and 121.30 may look different due to the extra zero at the end of Bill's total, but they actually represent the same value.

For determining which cyclist traveled with the greatest average speed, we first need to calculate the average speed for each cyclist using the formula:

speed = distance / time

After calculating, we compare the speeds to see which one is the greatest:

Cyclist 1: speed = 95 m / 27 s = approximately 3.52 m/s

Cyclist 2: speed = 87 m / 22 s = approximately 3.95 m/s

Cyclist 3: speed = 106 m / 26 s = approximately 4.08 m/s

Cyclist 4: speed = 108 m / 24 s = approximately 4.50 m/s

So, the cyclist with the greatest average speed is Cyclist 4.

Answer 2

C. Because you don't need the 0,0 is nothing so it is 121.3
