Answer:
The three numbers are : 9, 9 and 18
Step-by-step explanation:
Since the mean is 12 the sum of the three numbers must be 36. This is because:
(let the three numbers be x y and z)
(x+y+z)/3=12
(x+y+z)=12*3
(x+y+z)=36
And since the mode is 9 two of the numbers must be 9.
So to find the third number;
9+9+z=36
z=36-18
z=18
Answer:
D. 720 kmph
Step-by-step explanation:
Distance = rate • time.
First, we must find the distance covered when the airplane flies 240 km/hr in 5 hours.
D = 240 • 5
D = 1200 km.
Now the question is asking us, to travel 1200 km in 1 2/3 or 5/3 hours, how fast must we travel at? We can use the same equation, except this time we know the distance and the time, we need to solve for the rate.
1200 = r • 5/3
1200 ÷ (5/3) = r
1200 ÷ 5/3 = 1200 • 3/5 = 0.6 • 1200 = 720.
Therefore, the airplane must travel at a speed of 720 kilometers per hour.
