1.) 35,000+6,000+65+13
2.) 25,000+ 16,000+11,000+78
Answer:
4 [miles].
Step-by-step explanation:
1) the condition 'the entire trip took 5 hours' can be written as (where t_us - time spent upstream, t_ds - time spent downstream)

2) but the distance [D] upstream is equal the distance downstream, then the condition above can be written:

3) finally,

D=5*4/5=4 [miles].
can you make the question clear so I can answer you the question.
Answer:
Gradient = -5
Step-by-step explanation:
The gradient of a line is the slope of the line.
The standard form of the line equation is y = mx + b
where m is the slope ( or gradient) b is the y - intercept.
Given :
2y = -10x + 1

The slope of the line passing the points (1, 1) and (0, 0) is 1
<h3>Slope of a line</h3>
The formula for calculating the slope of a line is expressed as
Slope = y2-y1/x2-x1
Given the coordinate points (1, 1) and (0, 0)
Substitute the given coordinate points
Slope = 0-1/0-1
Slope = -1/-1
Slope =1
Hence the slope of the line passing the points (1, 1) and (0, 0) is 1
