Answer:
The answer to your question 4 hours
Step-by-step explanation:
Data
David = 16 mph
Corey = 28 mph
first time = 3 hours
time = ?
Formula
solve for distance
distance = v x time
Process
1.- Calculate the distance David travelled during 3 hours
distance = 3 x 16 = 48 m
2.- Write equations for the distance travelled by David and Corey
David = 16t + 48
Corey = 28t
3.- Equal both equations
16t + 48 = 28t
4.- Solve for t
16t - 28t = - 48
-12t = -48
t = -48/-12
5.- Result
t = 4 hours
