Greg is in a car at the top of a roller-coaster ride. The distance, d, of the car from the ground as the car descends is determi
1 answer:
The equation 
describes the relationship of he distance traveled and the time elapsed as one object travels a specified distance. This means that when t is 2 then d is 80. You know that a car is still in the air when the distance is a positive number and zero. The equation only holds true when t is at 0 to 3.

The volumetric rate or flow rate of a fluid is defined as the amount of the volume of a fluid circulating on a surface per unit of time. In this case we have units given initially: Gallons and minutes. For the first part we will convert the minutes to seconds, and we will obtain the flow rate under that measure. For the second case we will convert the gallons to cubic meters and obtain the desired value. Recall the following conversion rates,
If the flow rate is defined as the volume by time, the flow rate with the given values is
PART A ) Converting to Gal/seconds, we have,
PART B) Converting Gal/seconds to
