To find the distance the comet traveled, we can use the formula:
distance = speed x time
We know that the speed of the comet is 266,000 km/h, and it takes 7 days for the comet to reach Earth. However, we need to convert the time to hours, since the speed is given in km/h.
There are 24 hours in a day, so:
7 days x 24 hours/day = 168 hours
Now we can plug in the values we have into the formula:
distance = speed x time
distance = 266,000 km/h x 168 hours
Simplifying the right side of the equation, we get:
distance = 44,688,000 km
Therefore, the comet traveled a distance of 44,688,000 km to reach Earth.
