Laura and Cho designed and built two model cars. Laura built a green car. Cho built a yellow car. Their goal was to build a car that would roll at least 5 meters after reaching the bottom of a ramp. The table shows their test results.
Car - Distance Traveled
Green Car - 3.3 Meters
Yellow Car - 2.8 Meters
What is the next step that Laura and Cho should take?
A. keep testing their cars until they go farther
B. communicate to improve both of their designs
C. make the ramp taller so they don’t have to improve their car designs
D. conclude that the green car goes farther and give up on the yellow car
B. communicate to improve both of their designs
