t= time traveled by both the Scooter and the Bicycle
Scooter: 18t
Bicycle: bt=7
18 = 2b+4
2b = 14
Bicycle rate b = 7 mph
Scooter rate = 18 mph

The speeds from the other person are CORRECT!
Didn't see this: "Twice the rate"!

@MowMow, it is clear from your post, that you are not able to solve simplest Travel and Distance problem correctly
and have no idea on how to solve them, at all.

I observed your contribution to the forum,

and with 179% confidence I can say that you have no necessary knowledge to be a Math tutor.

I ask you STOP posting to this forum.

Dear tutor @MathTherapy,

I clearly see that the answer by @MowMow is correct.

But his solution is out of any logic.

It is why I protest against it.

We should not allow posting blatant nonsense to the forum.

SPEED TIME DISTANCE Scooter 2r+4 18/(2r+4) 18 Bicycle r 7/r 7

The two times were described as equal.
