Mulaney was participating in a 3-Day Walk for cancer. A friend pledged a flat $50 or $1 a mile which ever was more. If the walkers walked 6 hours a day and averaged 2.5 miles per hour, how much did the friend pay to charity?​

i hope this is what you were looking for.

see attached graph

you didn't give me the choices, so i will just give you the graph so you can look at your choices and choose the right one.

i believe it is 0.1m because the measurement of 30.4m limits how precise you can be

you can only be as precise as the least precise measurement
