Answer:
The difference between the distances they walked is 600 meters.
Step-by-step explanation:
Let's calculate the distance traveled by Nichol and Sakura with the following equation:

Where:
v: is the speed
t: is the time
The distance traveled by Nichol is:

And the distance traveled by Sakura is:

Hence, the difference between the distances they walked is:

Sakura traveled 600 meters more than Nichol.
Therefore, the difference between the distances they walked is 600 meters.

You can find the simplest form by dividing both the numerator and denominator by the GCF (greatest common factor). 100 divides into 100 and 1,000 equally so that can be the GCF used to reduce the fraction into its simplest form.


The simplest form is
.

One thing you could do is to expand either a factor of

or

, then expand the integrand. I'll do the first.
You have

which means the integral is equivalent to

Substitute

, so that

. This makes it so that the integral above can be rewritten in terms of

as

Now just use the power rule:

Back-substitute to get the antiderivative back in terms of

:
The answer would be 53,562. You would multiply 47400 by 1.13 to get your answer. Hope this helps!
Previous crime rate = c incidents per 1,000 people
Reduction in crime rate after batman brought the joker to justice = 12%
Hence, new crime rate (per 1,000 people) would be = c - 12%×c
⇒ New crime rate (per 1,000 people) would be = c - 0.12×c
⇒ New crime rate (per 1,000 people) would be = 0.88×c
Hence, now the crime rate is 0.88×c per 1,000 people.
