Final answer:
The car, traveling at a constant speed, travels 22.5 miles in 18 minutes, calculated by determining the car's speed from the information provided and then using it to find the distance covered in the specific time.
Step-by-step explanation:
To find out how far the car travels in 18 minutes, we need to calculate the car's speed and use it to determine the distance covered in the given time. Since the car travels 75 miles in 60 minutes, we can calculate its speed as follows:
Speed = Distance ÷ Time
Speed = 75 miles ÷ 60 minutes = 1.25 miles per minute
Now, to find the distance traveled in 18 minutes at the constant speed of 1.25 miles per minute, we multiply the speed by the time:
Distance = Speed × Time
Distance = 1.25 miles/minute × 18 minutes = 22.5 miles
The car travels 22.5 miles in 18 minutes.
