Answer:
It travels 1/5 mile in one second
Step-by-step explanation:
1/10 * 2 = 2/10 = 1/5
Since the bolt of lightning travels 1/10 mile in half a second, then to find how much it travels in one a second you simply multiply 1/10 by 2, which equals 2/10, which can be simplified to 1/5.
-17/9
In the sequence 5,10,20,40,80.. I can see that it is doubled each time.
Doubling 5 is 10, doubling 10 is 20, doubling 20 is 40, and doubling 40 is 80.
Good luck! Stay safe!
