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.

Answer:
17
Step-by-step explanation:
Let the larger number be represented by x
Let the smaller number be represented by y
from the question, the next equations can be gotten :
x - y = 9 equation 1
x = 1 + 2y equation 2
Substitute for x in equation 1
1 + 2y - y = 9
1 + y = 9
Collect like terms
y = 9 - 1
y = 8
Substitute for y in equation 1 and solve for x (the larger number)
x - 8 = 9
x = 9 + 8
x = 17
