Answer:
- 299,792 km
- 599,585 km
- 899,377 km
- 1,199,170 km
- 1,498,962 km
Explanation:
You want to find the distance traveled by light in km for periods of 1–5 seconds at a speed of 299,792,458 m/s.
Units
The speed is given in meters per second, and the table values are wanted in kilometers. There are 1000 meters in 1 km, so it can be convenient to convert the speed to km/s before doing other calculations.
(299,792,458 m/s) / (1000 m/km) = 299,792.458 km/s
Distance
The distance is found by multiplying the speed by time:
d = 299,792.458t
It is convenient to let a calculator do the multiplication (and rounding). The attachment shows the result of using t = {1, 2, 3, 4, 5}.
The distances are, respectively, {299792, 599585, 899377, 1199170, 1498962} km.
