The magnitude of the displacement the person traveled is 0.

Solution:

Starts driving and 3 km east to a store.

⇒ Distance = 3 km

Displacement = 3 km

Turns around and travels 1 km west to another store.

⇒ Distance = 1 km

Displacement = -1 km

Person travels 2 km west, back to the starting point.

⇒ Distance = 2 km

Displacement = -2 km

Magnitude of the displacement this person traveled

                    = 3 km + (-1 km) + (-2 km)

                    = 3 km - 1 km - 2 km

                    = 3 km - 3 km

                    = 0

The magnitude of the displacement the person traveled is 0.

The table shows the record monthly high and low temperatures for a city in Alaska.
Neko [114]
A. The range is equal to the highest value minus the lowest value. Since the table given in part A is already in terms of range, then there is no need for a solution. The range of temperature for each month is as it is.

B. For this question, find the largest value which would represent the all-time high. That would be on February at 95°F. The lowest value would also represent the all-time low. That would be on July at 50°F.

C. The range of part B is just the difference of the all-time high and all-time low temperatures.
Range = 95°F - 50°F = 45°F
