A probe launched from Earth to Mars is traveling at an average speed of 1.8 * 10^4 kilometers per hour. If the distance between Earth and Mars is approximately 2.25 * 10^6 kilometers, about how many hours will it take the probe to reach Mars?
PLEASE EXPLAIN YOUR REASONING
Speed is distance traveled over time, or
v = d/t
Since we're solving for time, we can rearrange the formula for time:
t = d/v
Substitute the values.
t = 2.25 x 10^6 / 1.8 x 10^4
t = ?
Units in hours. Hope this helps~ `u`
tysm once again Jai you da bomb
To find the time it will take for the probe to reach Mars, we can use the formula:
Time = Distance / Speed
In this case, the distance between Earth and Mars is given as 2.25 * 10^6 kilometers, and the speed of the probe is given as 1.8 * 10^4 kilometers per hour.
Let's substitute these values into the formula:
Time = (2.25 * 10^6 kilometers) / (1.8 * 10^4 kilometers per hour)
To divide by a fraction, we can multiply by its reciprocal:
Time = (2.25 * 10^6 kilometers) * (1 hour / 1.8 * 10^4 kilometers)
Now, we can simplify the expression:
Time = (2.25 * 10^6) / (1.8 * 10^4)
When dividing numbers in scientific notation, we can divide their coefficients and subtract their exponents:
Time = 1.25 * 10^2
So, it will take approximately 125 hours for the probe to reach Mars.
