Algebra.Com's Answer #302015 by htmentor(1343)![]() ![]() You can put this solution on YOUR website! Train A has traveled for 12 minutes at 100 mph by the time train B reaches the station. \n" ); document.write( "First convert 12 minutes to hours: \n" ); document.write( "12 min * 1 hr/60 min = 1/5 hr \n" ); document.write( "When train B reaches the station, the trains are separated by a distance \n" ); document.write( "d = 1/5*100 = 20 miles \n" ); document.write( "The relative speed of the two trains is 125 - 100 = 25 mph \n" ); document.write( "So the time required for train B to catch train A is: \n" ); document.write( "20 mi/25 mi/hr = 4/5 hr = 48 minutes \n" ); document.write( "So the time will be 48 minutes after 11:22 pm, which is 12:10 am \n" ); document.write( " |
