60,250,000,000,000,000 km correctly expressed in scientific notation is 6.025 x 10¹⁶ km

Explanation:

Scientific notation is a quick way to represent a number using base ten powers. This notation is used to express very large or very small numbers very easily.

The numbers are written as a product:

a*10ⁿ

where:

To write very large numbers in scientific notation, as in this case, first move the decimal point to the left as many spaces until it reaches the right of the first digit, thus obtaining the value of "a" from the previous expression. In this case this is expressed as:

a=6.025

To get the exponent n of the previous expression, you simply count the amount of spaces that you moved the comma. So in this case n = 16

Finally, 60,250,000,000,000,000 km correctly expressed in scientific notation is 6.025 x 10¹⁶ km

what is the general relationship between a galaxy's distance from earth and its speed?

the answer is:

the farther away a galaxy is from us, the faster it is moving away from us.
