I used the easy track for this.
Also, I had to plug in a second controller to activate the 2 player setting.
PUT THE TIME TO THE LOWEST SETTING:
you will only need 90 points to get the extend time bonus
I used the first controller to be the front of the fire truck.
You will have to use slight adjustments to the truck movements for the turns.
I did not brake or slow down.
I also used the d-pad, since i could never get the analog stick to turn where I wanted.
You can travel perfectly normally when the back of the truck is not straight.
The trick is DONT HIT ANYTHING, NEAR THE EDGE OF THE ROAD, OIL, ETC.
Even the slightest touch will cause you to crash, and you won't have enough time.
Also, if the back is too crooked it will slow you down, so nudge the back of the truck
to a lesser angle.
You will have to play through several times to get a feel for the track.
Here's my run through of it:
