Final answer:
Upon calculating the speed of travel as 2.5 miles per hour, the distance that can be traveled in one hour on a skateboard is 2.5 miles, which corresponds to option d).
\Explanation:
The question is asking how far you can ride on a skateboard in one hour if you can ride 1/2 mile in 1/5 of an hour. To solve this, we need to find the speed and then use it to calculate the distance traveled in one hour.
First, we calculate the speed using the information given. If you can travel 1/2 mile in 1/5 of an hour (12 minutes), then your speed is:
Speed = Distance ÷ Time
Speed = (1/2 mile) ÷ (1/5 hour) = (1/2) ÷ (5/1) = 5/2 miles per hour
This means that in one hour, at the same speed, you can ride:
Distance = Speed × Time
Distance = (5/2 miles per hour) × 1 hour = 5/2 miles = 2.5 miles.
Therefore, the correct answer is 2.5 miles, and the option d) is the correct choice.
