Let the time that you caught up with your friend be t, then
8.5 - 3.4t = 8 - 3t
3.4t - 3t = 8.5 - 8
0.4t = 0.5
t = 0.5/0.4 = 1.25
therefore, you will catch up with your friend after 1.25 hours.
b.) time it will take you to cross the finnish line = 8.5/3.4 = 2.5 hours
After 2.5 hours, distance covered by your friend = 3 x 2.5 = 7.5 miles
Therefore, when you cross the finish line, you are 8 - 7.5 = 0.5 miles ahead of your friend.
The space diagonal will have length ...
... d = √(1² +4² +2²) = √(1 +16 +4) = √21
_____
This can be found using the Pythagorean theorem. A drawing can help. Find the length of any face diagonal, then use that length as the leg of a right triangle whose hypotenuse is the space diagonal and whose other leg is the edge length not used in the first calculation.
7 because 42 divided by 6= 7 and length times width = perimeter
Hello there! Shelly ran D) 5/10 more miles than Ben.
To find the difference between the two runner's distances, subtract the smaller distance from the greater distance.
8/10 - 3/10 = 5/10
Since there is a difference of 5/10, this means Shelly ran 5/1 more miles.
I hope this helps, & have a great rest of your day! :)
