Answer:
The rate of the boat in still water is 73 km per hour, and the speed of the current is 24 km per hour.
Step-by-step explanation:
Given that a motorboat travels 441 kilometers in 9 hours going upstream and 388 kilometers in 4 hours going downstream, to determine what is the rate of the boat in still water and what is the rate of the current, the following calculation must be performed:
Upstream = 441/9 = 49 km per hour
Downstream = 388/4 = 97 km per hour
(97 + 49) / 2 = X
146/2 = X
73 = X
97-73 = 24
49-74 = -24
Therefore, the rate of the boat in still water is 73 km per hour, and the speed of the current is 24 km per hour.
You're question is:
- 0.35 - (-0.25)
Note that two negatives = one positive
-0.35 - (-0.25) = -0.35 + 0.25
Combine. Subtract.
-0.35 + 0.25 = 0.25 - 0.35
0.25 - 0.35 = - 0.1
-0.1 is your answer
