Answer:
b. One in Five
Step-by-step explanation:
To calculate probability, we need to know the formula: 
in this case the probability is given in its decimal form, which is = 0.20
∴ to be able to use our formula easily, we will need to convert the probability to its fraction form.
which is 0.20 =
(<em> to do this, just simply put a 1 under the decimal point and replace the remaining values of 20 with zeroes)</em>
reducing
to its simplest form gives
.
Hence, relating it to our formula, we can see that the number of possible out comes is = 1
and the total number of outcomes = 5.
This means that the probability that the order will execute before the same of closing is the same as 1 in 5

Answer:
5091 Km/hr and 505 km/hr
Step-by-step explanation:
Speed = Distance / Time
Let the speed of first automobile be 'x' and that of the second be 'y'
Since speed of one is 10 times greater than the other. therefore;
⇒ x = 10 y
also let time for faster automobile be 'T' and time for slower auto mobile be 't'
Since first arrive one hour earlier than second, therefore;
⇒ t = T + 1
⇒ For first automobile;
; substituting for 'x' and 'T'. Therefore;
⇒ 
⇒ For Second automobile;
⇒ 
⇒ 
⇒ 5600 +
= 560
⇒ 5600 - 560 = - 
⇒ t = 1.11 hr
also ; T = 1.11 - 1 = 0.11 hr
Speed of 1st auto = 560/0.11 = 5091 km /hr
Speed of 2nd auto = 560/1.11 = 505 km/hr
