To find out how far light travels in 6.8 seconds, we need to multiply the distance it travels in one second by 6.8.<br /><br />Given that light travels $3\times 10^{5}$ kilometers in one second, we can calculate the distance it travels in 6.8 seconds as follows:<br /><br />$3\times 10^{5} \times 6.8 = 2.04\times 10^{6}$ kilometers<br /><br />Therefore, light travels $2.04\times 10^{6}$ kilometers in 6.8 seconds.
