Final answer:
Calculating travel times and distances is a mathematical application. For Part C, one needs to determine the minimum speed to travel a certain distance in 5 minutes. Part D requires calculating how long it would take for Marine 1 to cover a distance at 30 mph and report it in minutes.
Step-by-step explanation:
The question revolves around calculating travel times and distances, which falls within the realm of mathematics.
We have two parts, C and D, with two different scenarios for transportation.
Part C
Let's assume the distance from the White House to the Lincoln Memorial is 'd' miles.
To find the minimum speed required to cover the distance 'd' in 5 minutes, we use the formula speed = distance/time. First, convert 5 minutes to hours by dividing by 60, as there are 60 minutes in an hour.
The formula becomes speed = d/(5/60) hours. Now, calculate the speed and round it to the nearest tenth of a mile per hour.
Part D
For Marine 1 to travel from the White House to the Lincoln Memorial at a speed of 30 mph, the formula time = distance/speed is used to calculate the travel time.
Assuming the distance 'd' is known, insert the given speed of 30 mph and solve for the time 't'.
Then, convert 't' from hours to minutes by multiplying by 60, as there are 60 minutes in an hour.
Finally, round the time to the nearest minute.
For both of these scenarios, specific distances are required to calculate the exact speed and time.
Without the distance 'd', the calculation cannot be completed.
