Question

What does D(4) = 1500 represent in the context of driving from El Paso to New York?

a) The distance you have traveled after 4 hours of driving.
b) The distance you have left to travel after 4 hours of driving.
c) The average speed at which you have been driving for the past 4 hours.
d) The average speed at which you need to drive in order to reach New York in 4 hours.

Answer 1

D(4) = 1500 likely represents the distance traveled after 4 hours of driving, not the distance left, the average speed driven, or the required speed to reach the destination in 4 hours.

Step-by-step explanation:

The statement D(4) = 1500 in the context of driving from El Paso to New York most likely represents the distance you have traveled after 4 hours of driving.

This is a typical notation used in functions where D might denote 'distance traveled' and (4) denotes the time in hours. To calculate the average speed, you would divide the distance traveled by the time. For example, if a car covers 150 kilometers in 3.2 hours, the average speed is calculated by dividing the distance (150 km) by the time (3.2 h), yielding approximately 47 km/h.
