What's next?

study_buddy99 · Answer

good, so now you make an equation (I'm doing c)

study_buddy99 · Answer

because zach did not get a head start the equation would be 30=4x. After solving for x you should get 7.5 minutes until he reaches 30 ft

study_buddy99 · Answer

However, since Brittany got a head start the equation is 30=3x+5. When solving for x you should figure out Brittany took 8.3 minutes to climb the wall, thus making her slower

then just create the table and graph
