Step-by-step explanation:
Answer:
P (A) = 0.45
Step-by-step explanation:
The addition rule of probability states that:

Given:

Compute the value of P (A) as follows:

Thus, the probability of <em>A</em> is, P (A) = 0.45.
4x+7=5x-4
-4x -4x
7=x-4
+4 +4
11=x
Firstly change the time into sec.that is
1 min=60 sec
5 min=60 into 5
=300 sec
speed=distance/time
=62.5/300
=0.20833333333333.............
- 4(1/2)x - (3/7) = (1/4)
- 4(1/2)x = (1/4) + (3/7)
- (9/2)x = (7+12)/28
-(9/2)x = 19/28
x = (19/28) * 2 / 9
x = (19/14) / 9
x = 19 / (14*9)
x = 19 / 126
