Answer 2

The way through which a very small or a very large number can be written in shorthand. The distance travelled by jet is $3 \times 10^9$ feet.

What are Scientific notation?

The way through which a very small or a very large number can be written in shorthand. In scientific notations when a number between 1 and 10s is multiplied by a power of 10.

For example, 6,500,000,000,000 can be written as 6.5e+12.

As it is given that the rate at which the jet flies is $1.3 \times 10^6$ feet per hour, while the time for which the jet flies is $2.8 \times 10^3$ hours. Now, the distance travelled by jet can be written as,

$\rm Distance = Speed \times Time$

              $= 1.3 \times 10^6 \times 2.8 \times 10^3\\\\=3.64 \times 10^9 \approx 3 \times 10^9$

Thus, the distance travelled by jet is $3 \times 10^9$ feet.
