Answer:

24/35 hours  or 0.69 hours

Step-by-step explanation:

we know that

The speed is equal to divide the distance by the time

Let

x-----> distance traveled by John

(24-x) ----> distance traveled by Ramona

The time is equal to divide the distance by the speed

so

x/20=(24-x)/15

15x=20(24-x)

15x=480-20x

15x+20x=480

35x=480

x=480/35 miles

the time is equal to

t=x/20

t=480/(20*35)=24/35=0.69 hours
