Answer: 44,94 km/h
Step-by-step explanation: 15 minutes is a quarter of hour. So we can write 4h + (1/4)h = 17/4 = 4,25 h.
As the average speed is calculated dividing distance by time, the result is 191/ 4,25 = 44,94 km/h.
Answer:
L = 2W, and LW = 5000. Therefore 2W^2 = 5000, so W^2 = 2500. This means W=50 and L=100.
Step-by-step explanation:
According to the given data we have the following equation:
|-ax-b|=c
So, to calculate the value of x we would have to apply the following property:
absolute rule
if |uI=a, a>o, then u=a or u=-a
Therefore, considering the propert above the calculation of would be as follows:
if a<0
-2x-1=-2
-2x=-1
x=1/2
if a>0
-2x-1=2
-2x=3
x=-3/2
The value of x would be 1/2 and -3/2
Is that a minus sign in between the x) and x=8?
