Question

Suppose it takes 3 days for a space vehicle to travel from the earth to the moon. About how long would it take the same vehicle traveling at the same speed to Venus? Moon= 240,000mi Venus=26,000,000mi
Round to the nearest whole number. Use scientific notation.
I know it is 325 but not sure how to do scientific notation please help

Answer 1

t= 26.000.000*3 / 240.000 = 325 days

Answer 2

That is not the scientific notation

Answer 3

The goal of writing a number in scientific notation is to have a decimal number, with one digit to theleft of the decmial point, followed by a × 10to some power.
To format your number in this way, we'll divide the 325 by 10, 2 time(s), making it a 3.25.
We do this, because each division by 10 moves the decimal point to the left one digit.
But in order to keep our number the same number, we must have a × 10^2 next to the 3.25.

So, the final answer is 3.25 × 10^2

Answer 4

CORRECTION
3x10^2 NOT 3.25
(multiplication, not just a plain x)
