If the velocity of a car is 45 km/h west how far can it travel in 0.5 hours?

A teacher uses the model that little invisible gremlins speed up or slow down objects and the direction they push gives the direction of acceleration.

Edson exercises in sets that are each t minutes long. He does 6 sets of push-ups, 3 sets of pull-ups, and 4 sets of sit-ups. Use an expression to represent the time it takes Edson to exercise as the sum of three different terms.
