Forces and Motion:Question 1 A rider on a bicycle travels north for 1.5 hours and covers a distance of 18

kilometers. What is the velocity of the bicycle?

Velocity = 12 km/h

Explanation:

Velocity can be defined as the division between distance traveled and the time it took for that distance to be traveled:

With the above information in mind, we can calculate the velocity of the bicycle:

Thus the velocity of the bicycle is 12 kilometers per hour.

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.

the answer is a for sure mark brainliest i had got this right on usatestprep
