Two trains leave a station at the same time, traveling in opposite directions. One travels 20mph faster than the other. In 4 hours, the trains are 900 miles apart. Find the speed of each train. Let x


Two corteges license a place at the similar age, traveling in contradictory directions. One travels 20mph faster than the other. In 4 hours, the corteges are 900 miles aloof. Find the urge of each cortege.

 Let x enact the urge travelled by cortege A,then the urge for cortege B procure be (x+20) Time=Total Distance/(Total Speed) less age is loving by 4hrs,and the completion urge is similar to sum of urge for cortege A and B and the completion space is 900 miles 900/(x+x+20 )=4 900/(2x+20)=4 cross-multiplying gives 8x+80=900,collecting approve stipulations and solving for x gives 8x=820 x=102.5 Therefore the urge for cortege A is loving by 102.5mph and that of cortege B is 102.5+20=122.5mph Thanks anticipation to product delay you in future
