But somebody should tell Tatiana's mom/dad to slow down (unless they are driving in Nevada).

The teacher would be right if they traveled 204 miles in 1 hour. But that's not what the problem says and I wouldn't call it driving.

Clearly the teacher is wrong. If Tatiana drove for 9 hours, then she traveled for 3*204 = 612 < 1428.

If they drove 204 miles in 3 hours then in 7 hours they drove (7/3)(204)= 7(68)= 476 miles. You could also calculate that they were driving at 204/3= 68 miles per hour.

From where did you get that?

Because all you'll hit in Nevada is cacti.

Since 9>7 one would expect that you would have driven further in 9 hours, than 7 hours! I picked 9 hours since it is larger than 7, the miles driven was easy to compute and the miles for 9 hours was less than the miles the teacher got for 7 hours.
