Question

Diego runs a 10 kilometer race and keeps track of his speed.

A. What is Diego's speed at 8 kilometer mark in the race?


B. According to the graph, where was Diego when he was going the fastest during the race?

Answer 1

A. 10 km/h

B. 6 kilometers into the race

Explanation:

Read from the graph.

The x-axis (along the bottom) is the distance in kilometers.

The y-axis (going up) is the speed in km/h.

A. Reading from the x-axis at 8, go up until you reach the line. Read to the left and we get 10 km/h.

B. Look at which point is the highest. Which is at 12 km/h where he was 6 km into the race.
