Along distance runner does a first lap around a track in exactly 50 seconds. as she tires, each subsequent lap takes 20% longer than the previous one. how long does she take to run 3 laps?

The first lap takes 50 seconds. Each subsequent lap takes 20% longer than the previous one.

So we can write the time taken to run the the lap is .

So we can write,

So the time taken to run 3 laps is

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
