Step-by-step explanation:
In order to describe speed of an object, we must describe the average speed of the entire trip. It is equal to the distance moved divided by time taken.
If a person covers a distance of 1 km to the library in 15 minutes, we can find its average speed.
Firstly, we convert 15 minutes to hour, 15 min = 0.25 hours
Now, using formula of speed = distance/time

It means that the average speed of the person is 4 km/h. Hence, the given statement is true.

.93 would have to be the answer because you do the regular calculations, then you divide to find y.
Answer:
-2 =x
Step-by-step explanation:
2 (x + 3 )= -x
Distribute the 2
2x+6 = -x
Subtract 2x from each side
2x+6-2x = -x-2x
6 = -3x
Divide each side by -3
6/-3 = -3x/-3
-2 =x
Answer:
46
Step-by-step explanation:
PR = PQ + QR
4x - 10 =<u> x + 2x</u> + 4 {Combine like terms}
4x - 10 = 3x + 4 {Add 10 to both sides}
4x = 3x + 4 + 10
4x = 3x + 14 {Subtract 3x from both sides}
4x - 3x = 14
x = 14
PR = 4x - 10 {Plugin x = 14}
= 4*14 - 10
= 56 - 10
= 46
