In four hours he would use 1.6 gallons. in 0.2 hours, he would use 0.08 gallons
total gallons would be 1.7 gallons
The nearest hundred will be in the hundredth place
For example, 2000
2 is in the thousands, followed by hundreds, ten, ones
to round to the nearest hundreds, you must look at the tens place (in this case 7) IF it is 5 or higher round the hundreds 1 number higher (+1) If it is 4 or lower, round all of the numbers including the number you are looking at to zero without changing the one in front of it.
So in this case 678 will equal 700
Example: if it were 644, then it would be 600
hope this helps
