Answer:

<em>Distance covered by motorcyclist A = 700 - 300 = 400 km</em>

<em>Distance covered by motorcyclist B = 300 - 0 = 300 km</em>

<em>The time before they met went for 5 hours</em>

<em>Average speed of motorcyclist A would be: 400/5 = 80 km/hour</em>

<em>Average speed of motorcyclist B would be : 300/5 = 60 km/hour</em>

Step-by-step explanation:

<u><em>In the given question first we have to find the distance covered by each of them.</em></u>

Look at the graph. Motorcyclist A started from 700 km and met at 300 km with motorcyclist B

Thus the distance covered by motorcyclist A = 700 - 300 = 400 km

Motorcyclist B started from 0 km and met with A at point 300 km.

Thus the distance covered by motorcyclist B = 300 - 0 = 300 km

<u><em>Now we have to find the time before they meet.</em></u>

Look at the graph. Both motorcyclists met at point t=5

Thus the time before they met went for 5 hours

<u><em>Now find out the average speed of motorcyclists</em></u>

To find the average speed we require total distance and time.

Motorcyclist A covered 400 km within 5 hours

<em>Average speed of motorcyclist A would be: 400/5 = 80 km/hour</em>

<em>Average speed of motorcyclist B would be : 300/5 = 60 km/hour</em>

the ratio of the sides of a certain triangle is 2:7:8 if the longest side of the triangle is 40cm how long are the other two sid
Zigmanuir [339]

The length of the other two sides is 10 and 35 respectively.

<h3>What is a ratio?</h3>

A ratio is a quantitative relation showing the comparison between two or more numbers. It can also be written in the fractional form where the first part is the numerator and the second part is called the denominator.

From the given information:

  • The sides of the triangle = 2:7:8
  • The total sides of the triangle = 2+7+8 = 17

We are being told that the longest side is the triangle is equal to 40.

i.e.

\mathbf{\to\dfrac{8}{17}\times x = 40}

\mathbf{x = 40 \div \dfrac{8}{17}}

\mathbf{x = 40 \times \dfrac{17}{8}}

x = 85

Now for the other two sides 2 and 7, their length is as follows.

\mathbf{\dfrac{2}{17}\times 85 = 10}

\mathbf{\dfrac{7}{17}\times 85 = 35}

Therefore, we can conclude that the length of the other two sides is 10 and 35 respectively.

You are correct!

90 would be the correct choice, here is why:

use the eqation: $20*30*15%

first times $20*30=600

now, 600 *15%= $90

therefore, your answer is 90 dollars
