Question

A frightened dot ran from −5 to 34. What distance did it cover? If the whole run took the dot 3 minutes, what was its average speed?

Answer 1

The average speed of the frightened dot was 13 units per minute.

Explanation:

Let's find out the distance covered by the frightened dot, as follows:

Distance = (Distance from - 5 to 0) + (Distance from 0 to 34)

Distance = 5 + 34

Distance = 39

Now, let's find out the average speed of the dot, this way:

Average speed = Distance/Time

Average speed = 39/3

Average speed = 13 units per minute
