We can interpret a distance traveled of 7.43 to mean a distance between 7.425 and 7.435 , thus rounding to 7.43 . Similarly, a time interval of 0.83 implies a time interval between 0.825 and 0.835 . Use these values to justify the rule for determining significant figures in division by finding the smallest and largest possible values of the speed.

A. vmax=
B. vmix=

l+sl= 7.435m

l-sl= 7.425m
