Her speed(relative to the ground) is 220 ft per minute. jose starts at the same time and walks alongside the walkway at a speed of 100 ft per minute. how long have they been walking when sadie is 600 ft ahead of jose? \n" ); document.write( ": \n" ); document.write( "Actually you can do this in your head using relative speed which is 120 ft/min \n" ); document.write( "600/120 = 5 min \n" ); document.write( ": \n" ); document.write( "Algebra way \n" ); document.write( "Let t = time (in minutes) for them to be 600 ft apart \n" ); document.write( ": \n" ); document.write( "220t - 100t = 600 \n" ); document.write( "120t = 600 \n" ); document.write( "t = \n" ); document.write( "t = 5 min \n" ); document.write( " \n" ); document.write( " |
