(3.) A tourist travels 320 km in 3.6 h. What is her average speed for the trip?

The average speed of the tourist is 88.89 km/h

Explanation:

Given;

distance of travel, d = 320 km

time of travel, t = 3.6 h

Average speed is given as;

average speed = distance / time

average speed = 320 km / 3.6 h

average speed = 88.89 km/ h

Therefore, the average speed of the tourist is 88.89 km/h

i guess it’s a and b

that tool is called an altimeter which measures your altitude which can be used to tell which atmosphere you are currently in, including the stratosphere.
