Aboat traveled 210 miles downstream and back. the trip downstream took 10 hours. the trip back took 42 hours. what is the speed of the boat in still water? what is the speed of the current?

16miles/hr

Step-by-step explanation:

Speed = distance/time

Distance = 210miles

Time downstream = 10hrs

So, Speed = 210/10 = 21miles/hr

Going through current time is 42hrs

Speed = 210/42 = 5miles/hr

Speed of current = (21 - 5)miles/hr

= 16miles/hr

the slope of the line is 60

one point on the line is (40,10)

step-by-step explanation:

in the equation outside the parenthesis the equation always tells you the slope. in this case it is 60.

in the parenthesis is also says 40 which is x because it is near the x and 10 is y because it is near y.
