The speed of light is = 3x10^8 m/sec. How long will it take to reach Pluto, 278,000,000,000 km away?
I don't understand how to set this problem?
time=distance/speed
so would it be
3x10^8mi/1sec x 1000km/1m x 60sec/1 min x 60min/1hr x and then what??
To calculate the time it takes for light to travel a certain distance, you can use the formula:
Time = Distance / Speed
In this case, the distance is given in kilometers, so we need to convert it to meters to match the unit of speed. Here's how to set up the problem:
1. Convert the distance from kilometers to meters:
Distance = 278,000,000,000 km * 1000 m/km = 278,000,000,000,000 m
2. Use the formula to calculate the time:
Time = 278,000,000,000,000 m / 3 × 10^8 m/s
Now let's calculate the answer:
