Math hw due asap #2? please?
The kansas city southern railway has a station in mexico city mexico. Suppose two trains leave mexico city at the same time. One travels east and the other west at a speed that is 10mph slower. In 1.5 hours, the trains are 171 miles apart. Find the speed of each train.
Comments
East bound train = x mph
West bound train = x-10 mph
Distance between them = 171 miles
171 = 1.5 ( x + x -10)
2x -10 = 114
2x = 124
x = 62
ANSWER 62 mph and 52 mph
CHECK
1.5 ( 62+52) = 1.5 X 114 = 171 miles
West bound is 52mph and east bound is 62mph.
West bound train is 10mph faster => will travel 15 miles more in 1.5 hours.
171 - 15 = 156mph/2 = 78mph what the slower train (east bound) has traveled in 1.5 hours. So, west bound train is at 52mph and east bound train at 62mph.
