Answer:
-12/5 = -1 2/5 = -1.4 and 6 1/2 = 13/2 = 6.5
Step-by-step explanation:
3 piano solos....each is 5/12 hr....
u can either add : 5/12 + 5/12 + 5/12 = 15/12 = 1 1/4 hrs
or u could multiply : 3 * 5/12 = 15/12 = 1 1/4 hs
either way....same answer
Answer:
The distance between them after 1 hour and 30 minutes will be of 63.64 miles.
Step-by-step explanation:
This question can be solved using the Pythagorean Theorem.
Both cars travel at a constant speed of 30 miles per hour. So, after 1 hour and 30 minutes, which is 1 and a half hour, they will have traveled 30*1.5 = 45 miles.
The distance between them is the hypotenuse of a right triangle, in which the sides are 45. So
![d^2 = 45^2 + 45^2](https://tex.z-dn.net/?f=d%5E2%20%3D%2045%5E2%20%2B%2045%5E2)
![d = \sqrt{45^2 + 45^2}](https://tex.z-dn.net/?f=d%20%3D%20%5Csqrt%7B45%5E2%20%2B%2045%5E2%7D)
![d = 63.64](https://tex.z-dn.net/?f=d%20%3D%2063.64)
The distance between them after 1 hour and 30 minutes will be of 63.64 miles.
