Stratovolcanoes – Mt. Vesuvius, Italy. Fly to Mt. Vesuvius in Italy and turn on the Pompeii Pyroclastic Flow tour (run the tour

twice to let the imagery load). Use the Ruler tool to determine the distance (in km) from Mt. Vesuvius to the excavated ruins of the city of Pompeii (which was buried by volcanic ash and pyroclastic material from Mt. Vesuvius during the eruption of 79 C.E.) If a nuée ardente (pyroclastic surge) accompanies the next eruption of Mt. Vesuvius and it travels at 300 km/hr, how many minutes would it take to reach the site of ancient Pompeii?

Answer:

The pyroclastic surge would take 1.609 minutes to reach the site of ancient Pompeii.

Explanation:

The ruins of Pompeii are about 5 miles away from Mount Vesuvius. A mile equals to 1.609 kilometers. If pyroclastic surge travels in a straight line at constant speed, then the time (t), in minutes, taken to reach the site of the ancient Pompeii can be determined by the following kinematic equation:

t = \frac{x}{v} (1)

Where:

x - Travelled distance, in kilometers.

v - Speed of pyroclastic surge, in kilometers per hour.

If we know that x = 8.045\,km and v = 300\,\frac{km}{h}, then the time needed to reach the site of ancient Pompeii is:

t = \frac{8.045\,km}{300\,\frac{km}{h} }\times 60\,\frac{min}{h}

t = 1.609\,min

The pyroclastic surge would take 1.609 minutes to reach the site of ancient Pompeii.

Which is the best definition for bias in history?
inna [77]
The opinions and prejudice of an author in writing.

I believe that those two elements greatly affect bias in history because we can never be 100% sure of everything that (may have) happened in history (especially farther in the past), so opinion can affect a historian's writings. Also, everyone is prone to some sort of prejudice, so this can also affect history.
