Answer:
Step-by-step explanation:
8x10^7
10^7 = 10,000,000
10 million times 8 = 80,000,000
5x10^5
10^5 = 100,000
100 thousand times 5 = 500,000
80,000,000 minus 500,000 = 75,000,000
so the distance from mason to chloe is 75,000,000 times greater than mason to kevin
i hope this was good, if it's not exactly what you need lemme know ^^
