Question 1 The y-axis, representing velocity, is scaled so that each square (vertical division) represents 5 m/sec. The x-axis is scaled so that each square represents 1 second.

What was the cart's instantaneous speed at 13.8 seconds?

-1.11 m/sec1.11 m/sec10.00 m/sec-10.00 m/sec cannot be determined
