a. Okay. So, it takes 4/5 hour (48 minutes) to complete 3 tasks. To find the answer, divide the amount of time by the number of tasks. 48/3 = 16. It takes the robot 16 minutes to complete 1 task.
b. So it takes 16 minutes to complete 1 task. To solve this, we can do 60/16. 60/16 is 3.75 or 3 3/4 in simplest form. But you can’t exactly count 3/4 as one task. The robot can only complete 3 tasks in one hour.
The mechanical advantage of a machine is the ratio of the force that you need to input to how much is outputted. 200:1000=1:5, meaning that the mechanical advantage is 5. Hope this helps!
