Answer:
speed = 67/6 miles per hour
Step-by-step explanation:
To find the average speed, we divide the distance by the time
d/t = 134 miles/ 12 hours
speed = 134/12 miles per hour
We can simplify this fraction by dividing the top and bottom by 2
speed = 67/6 miles per hour
Answer:
32.6 feet
Step-by-step explanation:
The computation of the height of the tree is shown below:
Data provided in the question
One position H = 60 degree
Second position L = 20
B = 40 degree
Based on the above information, the calculations are as follows
In triangle ZWX,
In triangle ZWY
Now from equation 1 and equation 2
i.e
Hence,
= 32.55190728
= 32.6 feet
Hence, the height of the tree is 32.6 feet
Since the formula for circumference is
2 pi r, you can multiply 28 by pi to get 87.92
Answer: 87.92
