Answer:
The answer to the picture is 19 square units if I remember correctly.
Step-by-step explanation:
X=1 so it is 1×1×1=1 so.... it is 19+1
Total distance = 200 miles
Time needed for the first 100 miles
= 100 ÷ 40 = 2.5 hours
Time needed for the second 100 miles
= 100 ÷ 50 = 2 hours
Total time = 2.5 + 2 = 4.5 hours
Average speed = 200 ÷ 4.5 hours = 44.4 miles per hour
