Could you please help me correct these sentences? How would you naturally say them?<br/><br/><br/><i>- I'm on/at <a href='http://www.abc.com' target='_blank' rel='nofollow'>www.abc.com</a>.</i><br/><br/><i>- He acts as if I'm not here/wasn't here.</i><br/><br/><i>- I've wrinkled/creased your sweater. (how to say this?)</i><br/><br/><i>- How many more miles to/till Paris?</i><br/><br/><i>- He's driving 3 times over the speed limit./3 times as fast as the speed limit.</i><br/><br/><i>- We have half as many miles to go before we arrive to our destination. (how to say?)</i><br/><br/><i>- This battery last four times as much/long.</i><br/><br/><i>- The line is longer at till 5/counter 5. (supermarket) how to say naturally?)</i><br/><br/>How come longer is correct and not shorter or is it?<br/><br/><i>It took less time /shorter to do that than this.</i><br/><br/><i>It took longer/more time to do this than that.</i><br/><br/><i>Thank you</i><br/>
