Question

Then, the dot ran from −17 to −81. What distance did it cover? If this run took the dot 8 minutes, what was its average speed?

Answer 1

Distance = 64 units

rate=8 units / minute

Explanation:

The distance from -17 to -81 is 64 units

81 - 17 = 64 units

Distance = 64 units

Distance = rate * time

We know the time is 8 minutes

64 = rate * 8

Divide each side by 8

64/8 = rate*8/8

rate=8 units / minute
