Final answer:
To calculate the distance the comet travelled, we multiply the average speed of 233,000 km/h by the time of 7 days converted to hours (168 hours), resulting in a distance of 39,144,000 kilometers.
Step-by-step explanation:
The student asked how to calculate the distance a comet travelled if it takes 7 days to reach Earth at an average speed of 233,000 km/h. To find the distance, we need to use the formula:
Distance = Speed × Time.
First, we convert 7 days to hours since the speed is given in km/h:
7 days × 24 hours/day = 168 hours.
Next, we multiply the time in hours by the speed:
Distance = 233,000 km/h × 168 hours = 39,144,000 km.
Therefore, the comet travelled a distance of 39,144,000 kilometers to reach Earth.
