If Mark is traveling South at 10 miles per hour for 45 minutes,
and Sally is traveling North at 5 miles per hour for 30 minutes,
and they meet after one hour, how far apart were they when they began?
:
The distance they were apart will equal the total distance they traveled.
:
Write a distance equation; d = speed * time
:
Change 45 min to .75 hrs, and 30 min to .5 hrs
:
d = 10(.75) + 5(.5)
d = 7.5 + 2.5
d = 10 mi apart
:
Not sure how "they meet after one hour" fits into this
