Answer:

5 years

Step-by-step explanation:

Given that

The current population is 45,000

The rate of interest in declining would be 4.5% per year

The expected population is 35,746

We need to find out the no of years

Since the rate of interest decrease by 4.5% per year so after decreasing it the percentage would be 0.955

Now

Year 1 = 45,000 × 0.955 = 42,975

Year 2 = 42,975 × 0.955 = 41,041.125

Year 3 = 41,041.125 × 0.955 = 39,194.27

Year 4 = 39,194.27 × 0.955 = 37,430.53

Year 5 = 37,430.53 × 0.955 = 35,746.16

Hence, the no of years would be 5

when Dallas committed to work one morning his average speed was 45 mph. On the return trip he average only 35 mph. Due to conges

defon

The required distance is 16.40 km.

This problem can be solved if we know the concept of speed, time and distance.

We know the speed= $\frac{distance}{time}$

To solve the problem let us assume that the total distance between the workplace and home is x km.

Given that his speed while going from home to work is 45 mph and while returning is 35 mph.

Time for the complete journey is $\frac{5}{6}hr$ .

Now according to question;

$\frac{x}{45}+\frac{x}{35}=\frac{5}{6}$

⇒ $\frac{7x+9x}{315}=\frac{5}{6}$

⇒ $16x=\frac{5*315}{6}$

⇒ $x=\frac{5*315}{6*16}$

∴ $x=16.40\ km$

So, the required distance is 16.40 km.
