Answer:
- boat speed: 17.25 mph
- current: 2.5 mph
Step-by-step explanation:
Upstream, the speed of the current (c) subtracts from the speed of the boat (b) to give the net speed. Downstream, the speed of the current adds. We can make use of the relation ...
speed = distance/time
b-c = 29.5/2 = 14.75 . . . . . miles/hour
b+c = 59.25/3 = 19.75 . . . .miles/hour
Subtracting the first equation from the second, we get ...
(b+c) -(b-c) = 19.75 -14.75
2c = 5
c = 2.5
Then either equation can be used to find b:
b = 14.75 +c = 17.25
The speed of the boat in still water is 17.25 miles per hour; the speed of the current is 2.5 miles per hour.
Well, yes and no.
Yes, because the straight line needs to pass through a number greater than 0, and 1 is obviously greater than 0.
However, y = x + 1 is not the same as y = x.
hope this helps.! let me know if it's in any way confusing..
I'd be happy to help!
Answer:
Step-by-step explanation:
÷ 
The reciprocal of is 3, so finding the reciprocal will replace the division sign with a multiplication sign.
= x 3
= or 1 or 1.5
Answer:
-t = -8 ×5
-t = -40
t= 40
good luck have a nice day
You can convert everything in minutes once you've solved it you turn it back to hours and minutes....5hrs and 8min= 308min....3hrs 12min=192min....308-192=116.....116 is 1hr and 56min
