Question

Elena and Jada are 24 miles apart on a path when they start moving toward each other. Elena runs at a constant speed of 12 miles per hour, and Jada walks at a constant speed of 8 miles per hour. How long (in hours) does it take until Elena and Jada meet?

Answer 1

Step-by-step explanation:

let time taken by both of them to meet be. t

distance traveled by Elena is x

distance traveled by jada is 24-x

x=t[12]. 24-x=t[8]

t=x|12. t=24-x\8

x\12=24-x\8

x=72\5. hr

x=14.4hr

Answer 2

Answer:

Step-by-step explanation:

The  total distance between Elena and Jada is 24 miles  

Now, it is also given that Elena runs at a constant speed of 12 miles per hour, and Jada walks at a constant speed of 8 miles per hour. Therefore, the total speed of both of them combined is 20 miles per hour.

Now, we know that the total time taken by Elena and Jada to meet will be given by dividing the total distance by total time.  

total time =  $\frac{24}{20}$ = 1.2

Therefore, It will take 1.2 hours for them to meet
