Question

A meteor travels for 2 x 10³ seconds at a speed of 5 x 10⁵ meters per second.
How far does the meteor travel in kilometers?​

Answer 1

Step-by-step explanation:

Distance = Speed×time

Distance = Speed×time Distance = 2 x 10³×5 x 10⁵

Distance = 10×10^8 metres

= 10^9 metres

Conversion into km

5×10^9 metres/1000 = 5 × 10^6 km

Answer 2

Answer 2*10³=2000sec

speed=5*10⁵=500000

Distance=speed*time

=500000*2000

=1000000000m/s

Now it convert into km/h

=1000000000*18/5

=36000000000
