A dot was running along a number line.
Then, the dot ran from 34 to −34. What distance did it cover? If this run took the dot 17 minutes, what was its average speed?

The distance would be 64 and 4 miles per hour would be its average speed.

Step-by-step explanation:

On a number line 34 to 0 is 34 points. And 0 to -34 is also 34 points. Add them together and you will get the distance. To find the average speed divide the distance by the time it took to cover that distance in this case 17 minutes and you will find the average speed of the dot.

x=-7

step-by-step explanation:

x+3=-10

-10+3=-7
