Answer:
Here x=10° ,2x=20° ,5x=50°
Answer:
Here we can use the relationship:
Distance = time*speed.
When Jose walks, his speed is 4 mph.
Then if he walks for X hours, the distance that he will travel is:
D = 4mph*X
When Jose runs, his speed is 8mph.
Then if he runs for T hours, the distance that he will travel is:
D´ = 8mph*Y
And we know that he travels in total 20 miles, then we must have that:
D + D´= 20mi
This leads to:
4mph*X + 8mph*Y = 20mi
Where X is the time that he walked, and Y is the time that he runed.
Then the equation that represents the different amounts of times that Jose runs and walks is:
4mph*X + 8mph*Y = 20mi
Where we can not really find the solutions for Y and X, because there is only one equation and two variables.
According to the Triangle Midsegment Thereom, if the midsegment of a triangle is parallel to a side of the triangle, then the midsegment is half the length of side it is parallel to, therefore...
45=(7x+13)/2
And after that, you continue to solve the problem using Algebra
90=7x+13
77=7x
11=x

Answer:
<h2>158,400 m. or 158.4 km.</h2>
Step-by-step explanation:
<u>distance = velocity x time</u>
where: time = 2 hrs. x 3600 sec / 1 hr
= 7200 secs
velocity = 22 m/s
plugin values into the formula:
distance = 22 m/s x 7200 sec.
= 158,400 m. or 158.4 km
