Answer:
60km
Step-by-step explanation:
There are two ways to look at this
1. Finding the unit rate
We can find how many km he travels in 1 hour by diving both the hours and km by 2. 1 hour = 10km so 6 hours is 60km since we multiply by 6.

20km * 3 hours = 60km

x = 9
Step-by-step explanation:
Solve for x:
x^2 - 18 x + 81 = 0

Take the square root of both sides:
x - 9 = 0
Add 9 to both sides:
Answer: x = 9
