The distance between the dog and cat is 6 miles. Then the equation is 30x = 6 or x = 0.2.
The distance covered by the particle or the body in an hour is called speed. It is a scalar quantity. It is the ratio of distance to time.
We know that the speed formula
[tex]\rm Speed = \dfrac{Distance}{ Time }[/tex]
Bobby's cat runs at x mph. Bobby's dog runs twice as fast as his cat.
The speed of a cat is x. Then the speed of the dog is 2x.
The distance traveled by the cat in 30 minutes will be
[tex]\rm D_c = 30 \times x\\\\D_c = 30 \ x[/tex]
The distance traveled by the dog in 30 minutes will be
[tex]\rm D_d = 30 \times 2x\\\\D_d = 60 \ x[/tex]
Suppose Bobby's cat and dog were 6 miles apart after 30 minutes.
[tex]\rm D_d - D_c \ \ = 6\\\\60x - 30x = 6\\\\30x = 6[/tex]
