Final answer:
Terry and Damon are 98 kilometers apart after Terry traveled 105 km from Sudbury towards Toronto, and Damon traveled 215 km from Toronto towards Sudbury, given the total distance between the cities is 418 km.
Step-by-step explanation:
The distance between Toronto and Sudbury is given as 418 km. If Terry left Sudbury and went 105 km towards Toronto, while Damon left Toronto and drove 215 km towards Sudbury, we can calculate the distance apart by subtracting the total distance they covered from the original distance between the two cities.
First, we add the distances each person traveled: 105 km + 215 km = 320 km. Then, we subtract this sum from the total distance between Toronto and Sudbury to find out how far apart Terry and Damon are.
418 km - 320 km = 98 km apart.
Thus, after their respective journeys towards each other, Terry and Damon would be 98 kilometers apart.
