Question

which unit is appropriate for measuring the time it takes for a piece of toast to cook?
seconds (s)
milliseconds (ms)
centiseconds (cs)
kiloseconds (ks)

Explanation:

Measuring toast cooking time requires a unit that matches typical durations (usually 10-60 seconds). Milliseconds and centiseconds are too small, kiloseconds (1000 seconds = ~16.7 minutes) are too large. Seconds are the appropriate everyday unit for this task.

Answer:

seconds (s)
