Question

A comet travels at an average speed of 273,000 km/h.

It takes 8 days for the comet to reach Earth.
Find the distance, in km, the comet travelled

Answer 1

Answer: 52,416,000 km

Explanation:

If a comet travels 273,000 km/hr

1) Multiply 273,000 km by 24 hours to find how far the comet travels in one day

2) multiply the answer from 1 by 8 to determine how far it travels in 8 days

1)
`(273,000 km)/(hr)`*
`(24 hr)/(1 day)` =
`(6,552,000km)/(day)` (hours cancel out)

2)
`(6,552,000km)/(day)`*8 day= 52,416,000 km in 8 days

The comet approximately travelled 52,416,000km from when it began to travel to when it reached Earth. Hope this helped :)
