Mr. Mole and Bugs Bunny started digging their way into the ground from different locations at the same time. They each dug at a constant rate. Mr. Mole's altitude (in meters relative to the ground) as a function of time (in minutes) is given by the following function: $A(t) =-4-0.6t$ Bugs Bunny's altitude (in meters relative to the ground) as a function of time (in minutes) is given by the following table of values: $\text{Time}$ (minutes) | $\text{Altitude}$ (meters) :-: | :-: $2$ | $-1.6$ $9$ | $-7.2$ $16$ | $-12.8$ **Who dug faster?** [[☃ radio 1]] **Who started at a higher altitude?** [[☃ radio 2]]
