Question

What number is most likely to be expressed in scientific
notation?
A
The distance between your home and your school
B
The top speed that your parents' car can travel
С.
The amount of money it costs to buy a new car
D
The speed of light

Answer 1

Answer: D) The speed of light

The speed of light is approximately $3 \times 10^8$ meters per second.

$3 \times 10^8 = 300,000,000$

In 1 second, a photon travels approximately 300 million meters

The other choices involve numbers that are well below the hundreds of million range, so scientific notation is not needed to shorten the number.
