Final answer:
To find the distance traveled by the car, multiply the constant speed (60 mph) by the time traveled (3 hours), resulting in a total distance of 180 miles.
Step-by-step explanation:
The student's question pertains to the calculation of distance traveled by a car moving at a constant speed for a certain period. Since distance is the product of speed and time, one can easily determine the distance by using the formula: Distance = Speed × Time. Given that the car travels at 60 miles per hour (mph) for 3 hours, the distance traveled can be found by multiplying these two values together:
Distance = 60 mph × 3 hours = 180 miles
Therefore, the answer to the student's question is option (b) 180 miles.
