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.
Answer: 116
Step-by-step explanation:
1.25 because 5/6 times 3 is 2.5 and that divided by 2 is 1.25
Answer:
4 pints
Step-by-step explanation:
There are 8 pints in one gallon, and 2 pints in one quart.
Carrie has 3 gallons of paint. 8*3 = 24 pints of paint.
Bryan has 10 quarts of paint. 10*2 = 20 pints of paint.
24 - 20 = 4. Carrie has 4 more pints of paint.
