where 
is the time in hours john has traveled since the gas station, and 
is the distance.
Now we know that John has already traveled 20 miles when he is at the gas station, this means at 
, 
; or
Thus we have
.

Answer:
Step-by-step explanation:
let x° be temperature when he woke up. Given that the temperature rose by 11° then later dropped by 14°. Also let 
be temperature at time she went to bed.
-We add the temperature rise and subtract the temperature drop to find temperature at time she goes to bed.
-The temperature relative to time of waking up can be expressed as:
Hence, the temperature relative to the time Iko woke up is (x-3)°
