Question

A river flows due south at 100 ft/min. A motorboat that travels 450 ft./min. in still water is headed due east across the river. Find the resultant speed of the boat.

round to the nearest ft./min.​

Answer 1

6x = 48

i hope this . 6 cards each and a total of $48. dvide each side by 6 and you will have your answer.

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth

Answer 2

The answer is : 461 ft./min

Explanation:

We can imagine the speed of the river (due south) and the speed of the boat(due east) as two vectors working at a single point with an angle of 90 degree . This allows us to use the parallelogram law to determine the resultant speed Of the boat.
