Question 1 The y-axis, representing velocity, is scaled so that each square (vertical division) represents 9 m/sec. The x-axis is scaled so that each square represents 1 second.

What was the cart's instantaneous speed at 14.3 seconds?

18.00 m/sec0.87 m/sec-0.87 m/sec-18.00 m/sec cannot be determined
