Step-by-step explanation:
Distance = rate × time
If b is the speed of the boat in still water, and c is the speed of the current, then:
60 = (b + c) × 4
35 = (b − c) × 3.5
Simplifying:
15 = b + c
10 = b − c
Add the equations together:
25 = 2b
b = 12.5
Plug into either equation to find c:
c = 2.5
The speed of the boat is 12.5 km/h, and the speed of the current is 2.5 km/h.
Answer:
Step-by-step explanation:
(1 3/5)/(2/5)
(8/5)/(2/5)
(8/5)(5/2)
40/10

Answer:
bus stop division really hard to show on here.
13/5
13 does not go into 5 so put a decimal point after the 5
13/5.000 carry the 5 over to the zero
13 goes into 50 3 times with 11 left over. carry the 11 over to the next zero. 13 goes into 110 8 times with 6 left over. carry over to the next zero. keep adding zeros and carrying over until the 13 goes into a number equally.
the answer is 0.38461538
Answer:25%
Step-by-step explanation: you find how many pieces there are than you find how many shaded parts. You then put it in a fraction that time is by hundred. That should get you to you percentage. I hope this helped. I also this is the correct answer :)
