Answer:
Dan did 5400 foot-pounds of work, and Louis also did 5400 foot-pounds of work.
Step-by-step explanation:
Work is calculated as force applied over a distance. In this scenario, the force is the weight of the individuals, and the distance is the height of the hill they climbed.
First, let's calculate the work done by Dan:
Dan's weight = 90 lbs
Height of the hill = 60 feet
Time taken = 10 minutes
Work (Dan) = Force × Distance
Work (Dan) = 90 lbs × 60 feet
Work (Dan) = 5400 foot-pounds
Now, let's calculate the work done by Louis:
Louis's weight = 90 lbs
Height of the hill = 60 feet
Time taken = 4 minutes
Work (Louis) = Force × Distance
Work (Louis) = 90 lbs × 60 feet
Work (Louis) = 5400 foot-pounds
So, the correct answer is:
Dan did 5400 foot-pounds of work, and Louis also did 5400 foot-pounds of work.
