Answer:
720 kph
Step-by-step explanation:
The ratio of times is ...
new time/original time = (1 2/3 h)/(5 h) = (5/3 h)/5 h) = 1/3
For the same distance, the ratio of speeds must be the inverse of this:
new speed/original speed = s/240 = 1/(1/3) = 3
s = 240(3) = 720 . . . . km/h
The aeroplane must travel at a speed of 720 km/h.

Answer:
Ix - 950°C I ≤ 250°C
Step-by-step explanation:
We are told that the temperature may vary from 700 degrees Celsius to 1200 degrees Celsius.
And that this temperature is x.
This means that the minimum value of x is 700°C while maximum of x is 1200 °C
Let's find the average of the two temperature limits given:
x_avg = (700 + 1200)/2 =
x_avg = 1900/2
x_avg = 950 °C
Now let's find the distance between the average and either maximum or minimum.
d_avg = (1200 - 700)/2
d_avg = 500/2
d_avg = 250°C.
Now absolute value equation will be in the form of;
Ix - x_avgI ≤ d_avg
Thus;
Ix - 950°C I ≤ 250°C
