Answer

3x10^17 meters

Work Step by Step

First, we know that 1 parsec is equal to 3.26 light years, so we can convert 9.6 parsecs to light years by multiplying by 3.26: 9.6 parsecs = 9.6 * 3.26 = 31.296 light years We know that the speed of light is 186,000 mi/s, so we can convert it to meters per second by multiplying by 1609.34: 186,000 mi/s = 186,000 * 1609.34 = 299,792,400 m/s We know that 1 light-year is the distance traveled by light in one year, which is the distance traveled at the speed of light in one year. So to find the distance in meters of an object that travels 9.6 parsecs, we can multiply the number of light-years by the speed of light. distance = 31.296 light years * 299,792,400 m/s *(365 days/1 year)*(24 h/1 day)*(60 min/1 h)*(60 s/1 min)\approx 3x10^17 m So, the distance of an object that travels 9.6 parsecs is 3x10^17 meters.
