Mario’s speed while riding his bike is shown in the graph. Amanda’s speed while riding her bike is 18 miles2 hours.

Which statement is true?

Mario’s speed is faster than Amanda’s speed.

Mario’s speed and Amanda’s speed are equivalent.

Amanda’s speed is 1 mile per hour faster than Mario’s speed.

Amanda’s speed is 10 miles per hour faster than Mario's speed.

I believe that it is C.

Step-by-step explanation:

Amanda's speed is 9 mph because 18 divided by 2 is 9.

Marcos speed is 8 mph because you can work backwards from the graph from the second point of (2, 16) to (1, 8) and find the difference of 1, and 8.

The slope is therefore 8.

Amanda's speed is 9 mph and Marco's speed is 8 mph. I think you know the answer from the previous statement.

1 is c

2 is a

3 is a
