A North American river otter wants to cross the North Saskatchewan river. It can swim at a speed of 2.75 m/s. In that location, the distance directly across the river is 45.0 m and the current velocity is 2.5 m/s. a) How much time does the otter take to get to the other side, if it points directly across the river?

time=16.3 sec

Step-by-step explanation:

let time taken be x

speed=distance/time taken

2.75=45/x

2.75x=45

x=45/2.75

x=16.36

x=16.3 seconds

the fist one is not equalvalent but i think th second one isand the third isnt definetly or the last one is i think. hope this !
