Two motorcyclist A and B, started simultaneously moving towards each other. From the graph given below, find the distance each o

harina [27]

Answer:

Distance covered by motorcyclist A = 700 - 300 = 400 km

Distance covered by motorcyclist B = 300 - 0 = 300 km

The time before they met went for 5 hours

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

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

Step-by-step explanation:

In the given question first we have to find the distance covered by each of them.

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

Now we have to find the time before they meet.

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

Thus the time before they met went for 5 hours

Now find out the average speed of motorcyclists

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

Motorcyclist A covered 400 km within 5 hours

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

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

The numbers of cars (c) in the parking lot increases when the parking fee (f) decrease. Write the correct equation for this scen

vodka [1.7K]

So when one goes up, the other goes down. This is an inverse equation.

An inverse equation looks like this: y = 1/x

In this case, when parking fee (f) decreases, cars (c) increase.
You know which side to put each variable on using the chart they gave you.
f | c
20.00 15 (20.00 = x/15) x=300
30.00 10 (30.00 = x/10) x=300

So your equation in this case is f = 300/c
Knowing that, plug in the fee of 6.00

6 = 300/c Multiply both sides by c.
6c = 300 Divide both sides by 6.
c = 50 cars

7. A shopkeeper buys 300 identical articles a tota

sashaice [31]

Step-by-step explanation and answers:

300 articles at a total cost of $1500:

$1500 / 300 = $5 / article

Sells 260 articles at a price 20% above this ^ price:

20% of $5 is $1, so $5 + $1 = $6

Then he sells 260 articles at the price of ^ $6

260 * $6 = $1560

Each of the remaining articles is sold at a price that's 50% of the 260 he sold.

He sold those for $6, so he would now sell the last 40 for $3

From the remaining 40 articles, he makes 40 * $3, or $120

The shopkeeper made $1560 + $120 = $1680, which is $180 more than he bought them for ($1500)

Therefore, he made a profit percentage of $180 / $1500, (the amount of profit over the amount spent).

He made a profit percentage, compared to the cost price, of 12%.
