The temperature fell from 0 degrees to 6 3/5 degrees below 0 in 2 1/5 hours. What was the temperature change per hour?

cestrela7 [59]

Answer: -3 degrees per hour.

Step-by-step explanation:

Given: The temperature fell from 0 degrees to $6\frac{3}{5}$ degrees below 0 in $2\frac{1}{5}$ hours.

The change in temperature= $0-6\frac{3}{5}$

$=-\frac{33}{5}$ degrees

Time taken to change the temperature= $2\frac{1}{5}=\frac{11}{5}$ hours

Now, the temperature change per hour is given by :-

$\frac{\text{Change in temperature}}{\text{Time}}=\frac{-\frac{33}{5}}{\frac{11}{5}}\\\\=\frac{-33\times5}{11\times5}=-3\text{ degrees per hour}$

What in a region can be affected by latitude, topography, altitude and closeness to a large body of water, jet streams and surfa

ELEN [110]

Answer:

Hey!

Step-by-step explanation:

Latitude, or how far one is from the equator, greatly affects the climate and weather of an area. If you live close to the equator, the climate will be warmer, while moving north or south from the equator brings a cooler climate. Altitude, or how high one is above sea level, has a similar effect–the higher the elevation, the colder the climate.

Hope this helps! :)

Have a nice day♥
