In winter, cold wind blows from North to South which brings dramatic decrease in temper- atures in Oregon. At t = 0 the temperature in Portland is 30° F and directly south of it, in Corvallis the temperature is 40° F. Joe Smith starts driving from Portland to Corvallis (at t = 0) with a temperature probe attached to the car antenna. The speed of his car is constant at 50 miles/hr throughout his journey and is exactly equal to the speed of the wind which is blowing southwards. The probe attached to the car antenna records an increase in temperature at the rate of 1° F/hr as the car moves southwards. Assuming linear temperature variation between Portland and Corvallis, find the temperature in Corvallis when Joe Smith arrives there. Assume distance between Portland and Corvallis is 100 miles Clearly indicate each term and its value in equations/laws you are using.

Linear Functions
A linear function can just be a constant, or it can be the constant multiplied with the variable like x or y. If the variables are of the form, x2, x1/2 or y2 it is not linear. The exponent over the variables should always be 1.
