Average speed for a driving 330 miles in 5 1/2 hours
Nookie1986 [14]
Here are some examples of basic distance problems.

Example 1: “A man has to bicycle 30 miles. He will travel at 6 mph. How long will it take?”

    The distance is 30 miles and the rate is 6 mph. We will plug these values into the formula, like so.

    To solve it, we need to divide both sides by 6.

    This means it will take 5 hours.

Example 2: “A bug travels at a rate equal to 3 inches per hour. How far will it travel in 4 hours?”

    The rate is 3 inches/hour and the time is 4 hours. We will plug these values into the formula, like so.

    To solve it, we need to simply multiply the values.

    This means it will travel 12 inches.

Example 3: “An asteroid travels 300,000 miles in 4 hours. How fast was it traveling?”

    The distance is 300,000 miles and the time is 4 hours. We will plug these values into the formula, like so.

    To solve it, we need to divide both sides by 4.

    This means it was traveling at 75,000 mph.
