Answer:
12/5
Step-by-step explanation:
Average speed is calculated by dividing the total distance travelled by the time interval. For example, someone who takes 40 minutes to drive 20 miles north and then 20 miles south (to end up at the same place), has an average speed of 40 miles divided by 40 minutes, or 1 mile per minute (60 mph).
20 the answer is 20 because you plug in 4 for n.
Look to be honest this is what I got hopefully it is right my bad if they aren’t.
