Two runners start 30kilometer apart and run toward each other. they meet after 3hours. One Runner runs 2 kilometers per hour fas
joja [24]

Answer:

4 km per hour and 6 km per hour.

Step-by-step explanation:

The combined running rate  = 30/3 = 10 km/h.

If one runner's speed = x then the other one's speed is x+2 km/h.

So x + x + 2 = 10

2x = 8

x = 4

So one runs at 4 km/h and the other at 6 km/h.

I'm having a hard time on this problem. Plz help. Will mark brainliest.
Grace [21]

Answer:

<h2>y = 31</h2>

Step-by-step explanation:

We know: opposite angles in a parallelogram have the same measure.

Therefore we have the equation:

x+y=87+y            <em>subtract y from both sides</em>

x=87

We know: the sum of the angle measures in the triangle is 180°.

Therefore we have the equation:

42+(x+y)+20=180          <em>subtitute x = 87</em>

42+87+y+20=180

149+y=180              <em>subtract 149 from both sides</em>

y=31
