First, it is important to know that speed is equal to distance divided by time. I took a picture of my work. Let me know if you still have questions or cannot read something I've written. Thank you!
The most Kilometers traveled per one hour was traveled by THE BOAT at 75 Km/h. Therefore, the boat had the fastestaverage speed.
I do know the bottom one is 2.8
Top is 1.6
I don’t know the middle one
The area of a triangle could be determined using the following formula
![\boxed{a= \frac{1}{2} \times b \times h}](https://tex.z-dn.net/?f=%5Cboxed%7Ba%3D%20%5Cfrac%7B1%7D%7B2%7D%20%5Ctimes%20b%20%5Ctimes%20h%7D)
plug in the numbers
![a = \frac{1}{2} \times 21 \times 12](https://tex.z-dn.net/?f=a%20%3D%20%20%5Cfrac%7B1%7D%7B2%7D%20%5Ctimes%2021%20%5Ctimes%2012%20)
![a = \frac{1}{2} \times 252](https://tex.z-dn.net/?f=a%20%3D%20%20%5Cfrac%7B1%7D%7B2%7D%20%5Ctimes%20252)
![a= \frac{252}{2}](https://tex.z-dn.net/?f=a%3D%20%5Cfrac%7B252%7D%7B2%7D%20)
a = 126
The area of the triangle is 126 square meters
Answer:
change inches into centimeter and then divide it
hope this help
Answer: 416 in^2
Step-by-step explanation:
a. Area of the Triangle x 2 + Area of Rectangle x 3
b. 8 x 7 / 2 x 2 + 8 x 15 x 3 = 56 + 360 = 416 in^2
