Two trains leave a train station at alike time. One travels east at 9 miles per hour. The other train travels west at 10 miles per hour. In how many hours will the two trains be 167.2 miles apart?
Answers: X = hours, in consequence 9X+10X = 167.2
19X = 167.2
X= 167.2/19
X = 8.8
9 x 8.8 = 79.20
10 x 8.8 = 88.00
time = 8.8 hours
Just a tip: it is 24 hrs in a daylight and 60 min. in a hour
you do the math using your average speed of travel and the total miles for your destination and the answer is................?
