First of all, the average speed is the ratio between the distance traveled and the time elapsed. So, the average speed of a car that travelled 720 kilometers in 6 hours is
kilometers per hour.
As for the second exercise, you can simply write this proportion:
Because we expect the distance traveled in 3 hours to be proportional to the distance traveled in 2 hours, if the (average) speed is the same.
Solving for x, we have
R + 4D < = 64 (thats less then or equal)....and R = regular and D = deluxe
100/5 = 20.
But, I'm not really sure how you want to do this.
Answer:
its the last one
Step-by-step explanation:
To find the rule of translation, find the change of corresponding coordinates. In this graph, for example see how A is moved to A': three units to the right, then two units down. A(-4,3)+(3,-2)=A'(-1,1). This applies to the whole shape, and is the rule of translation.
