Answer:
Helen: 60mph and Anne: 50mph
Step-by-step explanation:
3.2r+2.8(r-10)=332 is the equation that we use, given the information we have.
We distribute and combine like terms and add 28 to both sides and divide by 6.
3.2r+2.8(r-10)=332
3.2r+2.8r-28=332
6r=360
6r/6=360/6
r=60 So, Helen's speed is 60mph.
Next, we'll solve Anne's speed.
r-10=50
60-10=50 So, Anne's speed is 50mph.
The answer
let p' be the corresponding angle of the angle p (that is because of the prallelism and the transversal, look the image)
but p' and p are correspondant angles implies p'=p,
looking at the figure, p' and q are opposite angles
so q=p' and p'=p implies q=p
the answer is
<span>p = q</span>
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.
