First, we are going to find the radius of the yaw mark. To do that we are going to use the formula: 
where
is the length of the chord
is the middle ordinate
We know from our problem that the tires leave a yaw mark with a 52 foot chord and a middle ornate of 6 feet, so
and 
. Lets replace those values in our formula:
Next, to find the minimum speed, we are going to use the formula:
where
is <span>drag factor
</span>
is the radius
We know form our problem that the drag factor is 0.2, so
. We also know from our previous calculation that the radius is 
, so 
. Lets replace those values in our formula:
mph
We can conclude that Mrs. Beluga's minimum speed before she applied the brakes was 13.34 miles per hour.

Answer:
20 miles.
Step-by-step explanation:
Let m be number of miles.
Laguana's Truck Rentals charges $20 plus $2 per mile.
Total cost of Laguana's Truck = .... (1)
Salvatori's truck rentals charges $3 per mile.
Total cost of Salvatori's truck = ... (2)
We need to find the number of hours after that the total cost for both companies will be the same.
Therefore, after 20 miles the total cost for both companies will be the same.
