Question 405662
 Nedra and Latonya are 12 miles apart hiking toward each other. How long will it take them to meet if Nedra walks at 3mph and Latonya walks 1mph faster??
.
speed of Nedra: 3mph
speed of Latonya: 3+1 = 4mph
.
Let t = time walked
then
"distance walked by Nedra" + "distance walked by Latonya" = 12
3t + 4t = 12
7t = 12
t = 12/7
t = 1.714 hours
or
t = 1 hour and 43 minutes
