What is the unit rate if a car travels 180 miles in 3 hours?

Explanation:
Unit rate shows how far the car goes in one hour. To find it, divide the distance by the time: 180 miles ÷ 3 hours = 60 miles per hour. So the car’s speed is 60 miles per hour. You can check by multiplying back: 60 miles/hour × 3 hours = 180 miles, which matches the given distance. If the rate were 40 mph, 3 hours would give 120 miles; at 45 mph, 135 miles; at 75 mph, 225 miles. 60 mph fits exactly.
