Calculate the speed traveled for each situation below and then put them in
1 answer:
<h3><u>Put them in order from least to greatest</u></h3><h3>Moving 12 km in 40 minutes = 0.3 km/min</h3><h3>Moving 6 km in 15 minutes = 0.4 km/min</h3><h3>Moving 10 km in 20 minutes = 0.5 km/min</h3><h3>Moving 18 km in 30 minutes = 0.6 km/min</h3>
<em><u>Solution:</u></em>
<em><u>The speed is given by formula:</u></em>
<em><u>Moving 12 km in 40 minutes</u></em>
<em><u>Moving 18 km in 30 minutes</u></em>
<em><u>Moving 6 km in 15 minutes</u></em>
<em><u>Moving 10 km in 20 minutes</u></em>
<em><u>Put them in order from least to greatest</u></em>
Moving 12 km in 40 minutes = 0.3 km/min
Moving 6 km in 15 minutes = 0.4 km/min
Moving 10 km in 20 minutes = 0.5 km/min
Moving 18 km in 30 minutes = 0.6 km/min

So if you want to fit the y-intercepts or "b", on the y-axis you should go by 25's [0, 25, 50, 75, 100...]
If the x-axis <u>does not have to</u> follow the same pattern (25's), you should go by 5's [0, 5, 10, 15, 20...]
y = 7x + 50
y = 2x + 175
First I would plot the y-intercepts for each equation, then plot a few points with x = 5, 10, 15 Then draw a straight line.
The point where the two lines meet/cross paths is your solution. It should be (25, 225) The x-axis is the number of miles, and the y-axis is the total cost. So Truck driver A and B would arrive/be at the same place/meet in 25 miles at the same cost of $225
