Question

The speed of an aircraft is 1.024 * 10(3) km/hr.Express the distance it would travel in 2 hour 40 minutes in scientific notation ​

Answer 1

remember the formula for distance is

speed×time

time is 2hr 40min

1.024(10)*3×2.666667

now simple do calculation for answer is

1.024×1000×2.666667

1024×2.666667

is 2,730.67008 is distance travelled in km

Answer 2

speed=1.024*10^3km/hr.

=1024km/hr.

time=2hr.40min.

=2whole2/3

=8/3

distance=S*T

=1024*8/3

=8192/3

= 2,730.66667
