Answer:
Step-by-step explanation:
<em>Standard form</em>, also called <em>scientific notation</em>, is a more compact way of writing very big or very small numbers. All numbers in scientific notation have the form
where m is a number between 1 and 10, and b is an integer that represents how we've shifted the decimal point from the original number. For example, the number 23,000 in standard form would be written as 2.3 × 10⁴, since we have to shift the decimal point 4 places to the right to get back our original number.
We can turn 5,976,000,000,000,000,000,000,000 into a number between 1 and 10 by shifting the decimal 24 places to the left, giving us 5.976. We'll save that 24 as the exponent for our 10, giving us the final form

Any arithmetic sequence can be expressed as:
a(n)=a+d(n-1), a=initial value, d=common difference, n=term number.
The common difference is the constant difference found by subtracting the previous term from any term. In this case:
d=2-1 3/5=1 3/5-1 1/5=-2/5=-0.4 and we can easily see that the first term is 2 so
a(n)=2-0.4(n-1) which can be simplified...
a(n)=2-0.4n+0.4
a(n)=2.4-0.4n, so the 25th term is:
a(25)=2.4-0.4(25)
a(25)= -7.6 or if you prefer...
a(25)= -7 3/5
Answer: Train A - 60 mph; Train B - 125 mph
Explanation: To find the speed of Train A, you should do 120/2, which equals 60. To find the speed of Train B, you should do 250/2, which equals 125.
