Answer:
Speed of boat in still water = 64 km/hr
Speed of the current = 11 km/hr
Step-by-step explanation:
Let the speed of motorboat in still water = x km/hr
Let the speed of current = y km/hr
Motorboat travels 371 km in 7 hours going upstream.
Speed of motorboat while going upstream = speed of motorboat in still water - speed of current = (x-y)
=> ![\[x-y = \frac{371}{7}\]](https://tex.z-dn.net/?f=%5C%5Bx-y%20%3D%20%5Cfrac%7B371%7D%7B7%7D%5C%5D)
=> ![\[x-y = 53\]](https://tex.z-dn.net/?f=%5C%5Bx-y%20%3D%2053%5C%5D)
------------------------------(1)
Motorboat travels 525 km in 7 hours going downstream.
Speed of motorboat while going downstream = speed of motorboat in still water + speed of current = (x+y)
=> ![\[x+y = \frac{525}{7}\]](https://tex.z-dn.net/?f=%5C%5Bx%2By%20%3D%20%5Cfrac%7B525%7D%7B7%7D%5C%5D)
=> ![\[x+y = 75\]](https://tex.z-dn.net/?f=%5C%5Bx%2By%20%3D%2075%5C%5D)
-----------------------------(2)
Solving for x and y from (1) and (2):
Adding (1) and (2):
2x = 128
=> x = 64
Substituting the value of x in (1), y = 11
Answer:
The answer is 4 Days
Step-by-step explanation:
12/3=4
√16 = 4
Answer:
40 units
Step-by-step explanation:
On the number line, the distance between x and y is given by
|x-y|.
To find the distance between -70 and -30 on the number line, we find the absolute value of their difference.
Therefore the distance between -70 and -30 on the number line is 40 units.
The statement that is true concerning the function of the table compared to the graph is that the graphed function has a greater maximum value. That is option D.
<h3>Comparison of table function and graph</h3>
From the graph, the maximum value is =0.5 while the minimum value cannot be determined.
From the table the maximum value is -3 while the minimum value is -24.
Therefore, the statement that is true concerning the function of the table compared to the graph is that the graphed function has a greater maximum value.
