<p>Does anyone have any tips as to how I should approach/solve work problems (like if Bob and Mike can complete the job in 5 hours, how many hours will it take Jack and Bill to do it....)</p>
<p>and Speed problems (like he went to the house at 45 mph and returned 5 hours later at 10 mph). What was his avg speed/how far did he travel?</p>
<p>Thanks in advance.</p>
