Final answer:
Simpson travels a distance of 180 miles by driving at an average speed of 60 miles per hour for 3 hours.
Step-by-step explanation:
If Simpson drives his car with an average speed of 60 miles per hour and he travels for 3 hours, we can calculate the distance he goes by using the formula:
Distance = Speed × Time
So the distance Simpson travels is:
Distance = 60 miles/hour × 3 hours = 180 miles
Therefore, the answer is (c) 180 miles.
