Answer: 2.5x10^8 kilometers
Explanation:
Given that:
Distance between the earth and the sun = 2.5x10¹¹metres
Convert distance in metres to kilometers
Recall that 1000 metres = 1 kilometers
So, 2.5x10¹¹metres = Z kilometers
To get the value of Z, cross multiply
Z km x 1000 m = (2.5x10¹¹metres x 1km)
1000Z = 2.5 x 10^11
Divide both sides by Z
1000Z/1000 = 2.5 x 10^11/1000
Z = 2.5x10^8km
Thus, the distance between the earth and the sun is about 2.5x10^8km
