The distance (d) in meters that an ant can travel is proportional to the amount of time (t) in hours it spends walking. The unit rate for the ant is 18 meters per hour.
a. Write an equation representing the relationship between d and t using the information given.
b. If an ant walks at a constant speed for 10 minutes, how far will it travel?
c. If an ant traveled meters, how long did it walk?
