Mike drove 20 miles in a 1/2 hour. what is his unit rate in miles per hour? a 20 miles b 30 c 40 d 50

40 miles an hour

Step-by-step explanation:

Note that the speed given to you is in 1/2 an hour. To get 1/2 hour to become 1 hour, multiply by 2.

20 = 1/2h

20(2) = (1/2)h(2)

Simplify. Isolate the h. What you do to one side, you do to the other

20(2) = h

h = 40

40 mph is your answer

the function makes a strait line horizontally with no x intercept but a y intercept at 9.

i only know the sequence of arithmetic it adds the first is 5+4 then it goes up as it adds to then it is 9+5 then 14+6 then to 20+7 and so on. 5,9,14,20,27,35.
