Step-by-step explanation:
if each the bonus is shared equally each will get 420
if 40% is shared by managers each manager will get 560
if 7 sales persons share 60% each will get 360
therefore Peter salesperson will get 360
but he thinks he will get 336 because if 420 is 125% that is including his extra 25% then hundred percent of the 420 is 336 which is not what he will get there for Janet is correct
Part 1: The speed of the boat traveling downstream is miles per hr.
The speed of the boat traveling upstream is miles per hr.
Part 2: The speed of the current is 4 miles per hour.
Explanation:
Part (1): The motorboat travels 18 miles per hour in still.
Let w represents the speed of the current.
When the boat travels downstream, the speed of the current will get added to the speed of the boat.
Thus, the expression can be written as miles per hr
Hence, the speed of the boat traveling downstream is miles per hr.
When the boat travels upstream, the speed of the current will get subtracted to the speed of the boat.
Thus, the expression can be written as miles per hr.
Hence, the speed of the boat traveling upstream is miles per hr.
Part (2): The boat travels 49 miles upstream in the same time it takes to travel 77 miles downstream.
The distance formula is given by
Substituting, we have,
---------------(1)
---------------(2)
Solving using elimination method,
Dividing both sides by 36, we have,
Substituting in
, we get,
Thus, the speed of the current is miles per hour.
