Answer:

\frac{600}{x+20}\text{ litres per 100 km}

Step-by-step explanation:

Given,

The number of litres consumed by car in (x+20) km = 6,

So, number of litres consumed by car in 1 km = \frac{6}{x+20},

Now, number of litres consumed by car in 100 km = 100 × litres consumed by car in 1 km

=100\times \frac{6}{x+20}

=\frac{600}{x+20}

Hence, the rate of fuel used by his car would be \frac{600}{x+20} litres per 100 km.

Answer:

0.61

Step-by-step explanation:

The computation of the probability of the working of the system is shown below:

But before that first we have to find out the total probability of sub-system i.e 2,3 and 4 i.e

= 0.75\times0.8\times0.8

= 0.48

Now the working of the system probability is

= 1 - [(1 - probability of component 1) × (1 - sub system probability)]

= 1 - [(1 - 0.75) × (1 - 0.48)]

= 1 - 0.39

= 0.61

Please find the attachment for better understanding.
