If a train left Shawnee traveling due west at 90 miles per hour, a car left Shawnee at the same time traveling due east at 60 miles per hour, how much time will pass?
The answer to this problem is - t*90+t*60=405t*(90+60)=405t(150)=405t=405/150t=27/10t=2.7 hours or 2 hrs 42 minutesAre you sure the distance is not 450?IF it were 450 then we havet*(90+60)=450t*150=450t=3 hours ChaCha on!

About Hours
An hour consists of sixty minutes. We measure out our days in hours; when we are having fun, an hour is short. While we are suffering, an hour is very very long. In the Middle Ages (the 5th century to the 15th century) Christian monks and artists created 'Books of Hours.' They contained prayers and psalms for each hour of the day. They were 'illuminated,' that is, their texts were illustrated in gold ink and brilliant colors. The Cloisters Museum in NYC has a wonderful collection of Books of Hours.
