If i drive. at 60 mph for 120 minutes and then go 30 minutes at 20 mph how far did i travel

120 minutes is 2 hours so with that time a person has travelled 120 miles per hour. Now 20 miles per hour for 30 minutes half of an hour is thirty minutes so they have to divide the mph by 2. With this being said The second part he travels 10 miles.

In total he travelled 130 miles.

(1,4) is on graph of f(x)

f(1) = 4

so 1/4 f(x)

1/4 f(1)

1/4. ×4

1

so point for function 1/4. f(x) is (1,1)
