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
t= 26.000.000*3 / 240.000 = 325 days
That is not the scientific notation
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
CORRECTION
3x10^2 NOT 3.25
(multiplication, not just a plain x)
To calculate the time it would take for the space vehicle to travel from Earth to Venus, we can use proportions.
The distance from Earth to the Moon is given as 240,000 miles, and the distance from Earth to Venus is given as 26,000,000 miles.
Let's set up the proportion:
Distance to Moon / Time to Moon = Distance to Venus / Time to Venus
240,000 mi / 3 days = 26,000,000 mi / Time to Venus
To find Time to Venus, we can cross multiply and solve for the unknown:
240,000 mi * Time to Venus = 3 days * 26,000,000 mi
240,000 * Time to Venus = 78,000,000 days
Time to Venus = 78,000,000 days / 240,000
Time to Venus ≈ 325 days
To express this answer in scientific notation, we represent 325 as 3.25 x 10^2. The exponent indicates the number of places we need to move the decimal point to the right to obtain the final result. In this case, we move the decimal point two places to the right, resulting in a value of 325.
