Final answer:
To find the distance a truck will travel in 3 hours at 50 miles per hour, multiply the time by the speed to get 150 miles.
Step-by-step explanation:
To calculate the distance a truck will travel in 3 hours at an average speed of 50 miles per hour, we can use the basic formula for distance, which is the product of speed and time. The formula looks like this:
Distance = Speed × Time
Therefore, if a truck is moving at an average speed of 50 miles per hour for 3 hours, we multiply the two:
Distance = 50 miles/hour × 3 hours = 150 miles
So, the truck will travel 150 miles over the 3-hour period at the given speed.
