Sarah wants to find out how much time it would take to drive from her home to new york. at an average, she would drive at 55 miles per hour.

if the distance to be covered is 1150 km and a mile equals 1.61 km, how much time will the trip take (to the nearest hour)?

a. 13 hours
b. 21 hours
c. 29 hours
d. 34 hours

The correct answer is option is (A).

Explanation:

Distance from Sara's home to New York = 1150 km = 714.265 mile

1 mile = 1.61 km

Speed of the Sara: 55 mile/hour

The correct answer is option is (A).

in scientific notation, the value of the  speed of light in a vacuum

  will be written as 2.995 * 10^8. when this value is represented in the form of

  a * 10^b, then, a = 2.995 and b = 8.

the value of the speed of light in a vacuum given above can also be rounded up to approximately 300000000. in this case, the scientific notation will be written as 3 *10^8.

answer is: naturally occurring solid, inorganic compound or element is mineral.

minerals usually have crystalline form, that means than crystal constituents (atoms, molecules or ions) are arranged in a highly ordered microscopic structure, forming a crystal lattice that extends in all directions.

for example magnetite is a mineral of iron oxide (fe₂o₃).

calcite is a carbonate mineral and the most stable polymorph of calcium carbonate (caco₃).

dolomite is an   carbonate mineral composed of calcium magnesium carbonate (camg(co₃)₂).
