# What was the speed?

Algebra Level 3

One day I was traveling in an auto. The driver had started the meter at time $$t=0$$ and distance $$d= 0$$. When passed after a while, I had observed the reading on the meter to be $$t = 5\text{ min}$$ and $$d = 6\text{ km}$$ and thereon it was found that for every km traveled, the difference between the value of the distance and the time to be 1.2

What must be the average speed of the auto? (in $$\text{km/hr}$$)
