Step-by-step explanation:
It is given that,
The angle of depression is 30 degrees from the bottom of the boat to a deep sea diver at the depth of 120 ft.
We need to find the distance x the diver must swim up to the boat. It can be calculate by applying trigonometry as follows :
So, the distance the diver must swim up to the boat is 240 feet.

Answer:
Robot will take hour to complete each task.
The robot can complete tasks in one hour.
Step-by-step explanation:
We have been given that a robot can complete 8 tasks in 3/10 hour. Each task takes the same amount of time.
To find the time taken by robot to complete each task we will divide total time taken to complete 8 tasks by 8 as:
Now we will convert division problem into multiplication problem by flipping the 2nd fraction.
Therefore, robot will take hour to complete each task.
To find tasks completed by robot in one hour we will use proportions.
Therefore, the robot can complete tasks in one hour.
