Question

A jet flies at a rate of 1.3 * 10^6 feet per hour. Written in scientific notation, which is the best estimate of how many feet the jet will travel in 2.8 *10^3 hours?

Answer 1

C. 3x10^9

Explanation:

Answer 2

To determine the distance covered by the jet in a given time, we simply multiply the rate or velocity of the jet to the time elapsed. It is important to take note of the units. It should be homogeneous. We calculate as follows:

1.3x10^6 x 2.8x10^3 = 3.64x10^9 ft

Hope this answers the question. Have a nice day.
