Question

Elena and Jada are 12 miles apart on a path when they start moving towards each other Elena runs at a constant speed of 5 miles per hour and Jada walks a constant speed of 3 miles per hour how long does it take untill Elena and Jada meet? please explain answer. Thank you!

Answer 1

if you really want to figure this out you make an equation to solve for the time
let's let
x = time from Elena to Jada and
x = time from Jada to Elena
12 then the equation
12 = 5x +3x
would help figuring out their distance say for one of them
12 = x(5+3)
12/8 = x
1.5 = x
1. 5 hours they will meet up

Answer 2

Elena runs at a constant speed of 5 miles per hour and Jada walks a constant speed of 3 miles per hour it takes 1.5 hours to both of them to meet.

Given :

• Elena and Jada are 12 miles apart.

• Elena runs at a constant speed of 5 miles per hour and Jada walks a constant speed of 3 miles per hour.

Solution :

We know that the formula of speed is given by:

$\rm Speed = \dfrac{Distance }{Time}$

$\rm Distance = Speed \times Time$

Given that the total distance between Elena and Jada is 12 miles. Let Elena covers a distance 'a' and Jada covers a distance 'b' at time 'x' in hours.

Then total distance between each other is given by:

12 = a + b

12 = 5x + 3x

8x = 12

x = 1.5 hour

Elena and Jada meet after 1.5 hours.
