Step-by-step explanation:
Answer:
54 mph
Step-by-step explanation:
1 yard is 3 feet
1 foot is 12 inches
Convert everything into inches:
9 x 12 = 108 in.
6 x 3 = 18 ft.
18 x 12 = 216
Add the inches together:
108 + 216 = 324 in
Multiply the inches by 2:
324 x 2 = 648 in
The answer is 648 inches.
To find the mean, you need to find the average. The equation that I used was 61(1)+64(3)+67(5)+70(6)+73(5) and then divided that total by the total number of 20.
The answer would be D) 68.5
