Answer: 1.08x10⁹ km/hr
Step-by-step explanation:
1000 m = 1 km
So 1800000000 m = 1800000 km
60 seconds = 1 min
60 minutes = 1 hr
So 60x60 seconds = 1 hr
6 x 600 seconds = 1 hr
6 seconds = 1/600 hr
∴1800000000 m / 6sec = 1800000 km / (1/600) hr
=1800000 /(1/600) km/hr
=1800000 x 600 km / hr
=1080000000 km/hr
=1.08x10⁹ km/hr
