Question 520854: Mr. Anders and Mr. Rich each drove home from a business meeting. Mr. Anders traveled east at 100 kilometer per hour and Ms. Rich traveled west at 80 kilometers per hours. In how many hours were they 100 kilometers apart. Answer by Maths68(1474) (Show Source):
You can put this solution on YOUR website! Effective Speed = 100 + 80 = 180 kmph
Distance apart = 100 km
Time = Distance / Speed
Time = 100 / 180
Time = 0.556 hour
After 0.556 hour they will be (approximately)100 kilometers apart.
Check
=====
Mr. Anders will cover = Speed * time = 100*0.556= 55.60 km
Mr. Rich will cover = Speed * time = 80 * 0.556 = 44.48 km
After 0.556 hour they will be = 100.08 miles apart.
