During a race, Bernie ran

Define variables and write an equation for Bernie and an equation for Wendel. time in seconds

*distance in meters*

To catch up, their equations would need to be equal.

meters, remember to substitute

*back into one of the original equations to solve for*

*.*

Bernie can't catch up with Wendel in
