The average speed of a car during 5 hours is 50 miles per hour. What is the total distance traveled by the car? O 0.1 miles
O 10 miles
O 250 miles
O 500 miles

250 miles

The rate for 1 hour is 50 miles per hour. We must multiply 50 by 5 to find the distance drove in 5 hours.

50 x 5 = 250.

The answer to the question is 250.

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.

it's all four options.
