Adog runs at an average velocity of 1.40 m/s south for 89.0 sec, and then walks at an average velocity of 0.45 m/s in the same direction for
98.0 sec. what is the average
velocity of the dog during its total time of travel?

neither accurate nor precise.

the old price per ounce is c/4.

the new price per ounce is c/3.6.

the ratio of the old price to the new one is

(c/4)/(c/3.6) = (c/c)×(3.6/4) = 0.9 . . = 9/10 . . "nine tenths" in either form
