$93\times 10^6\ miles = 1.49\times 10^{11}\ meters$

Explanation:

It is given that, the sun ,on average, is 93 million miles from earth. We need to write this distance in meters. The relation between miles and meters is as follows :

$1\ mile=1609.34\ meters$

Also, $1\ million=10^6$

$93\ million\ miles=93\times 10^6\ miles$

$93\times 10^6\ miles = 93\times 10^6\times 1609.34$

$93\times 10^6\ miles = 1.49\times 10^{11}\ meters$

So, the Sun is 93 million miles or $1.49\times 10^{11}\ meters$ away from the earth. Hence, this is the required solution.
