Final answer:
A car moving at a constant speed of 55 mph for three hours travels 165 miles; this is calculated using the formula distance = speed x time.
Step-by-step explanation:
The question is how far a car traveling at a constant speed of 55 mph will go in three hours. To solve this, we use the formula for distance which states distance = speed × time. Since the car is moving at a constant speed of 55 mph, we can simply multiply this speed by the time the car is traveling to find the distance.
If we let D represent distance, S represent speed, and T represent time, our formula looks like this:
D = S × T
Plugging in the values:
D = 55 mph × 3 hours = 165 miles
Therefore, the car travels 165 miles in three hours.
