Final answer:
A pedestrian traveling at 3mph will travel approximately 2 miles in 40 minutes.
Step-by-step explanation:
To find the distance traveled by a pedestrian at a speed of 3mph for 40 minutes, we can use the formula distance = speed x time.
First, convert the time from minutes to hours by dividing 40 minutes by 60. This gives us 0.67 hours.
Then, multiply the speed of 3mph by the time of 0.67 hours to get the distance traveled. The answer is approximately 2 miles.
