The speed is the distance covered by an object at a particular time. The time taken by Danny and his sister Elise to meet is 1.2 hours.

What is speed?

The speed is the distance covered by an object at a particular time. Therefore, it is the ratio of distance and time.

[tex]\rm{Speed = \dfrac{Distance}{Time}[/tex]

Given that Danny and his sister Elise are 24 miles apart. Danny rides at a rate of 8 miles per hour, and Elise rides at a rate of 12 miles per hour. Therefore, we can write,

Distance to cover = 24 miles

Since they are moving toward each other, therefore, the relative speed will be,

Relative speed = 8 miles per hour + 12 miles per hour = 20 miles per hour

Now, the time taken them to meet each other is,

Time = Distance / Speed

Time = 24 miles / 20 miles per hour

= 1.2 hours

Hence, the time taken by Danny and his sister Elise to meet is 1.2 hours.
