When using division or multiplication, the number of significant figures should be no more than the factor with the least number of significant figures. In this case, you have 35.896/6.25 so the answer should have only 3 significant figures (based on 3 SF in 6.25). The answer would be 5.74 m/sec.

∙ 7y agoAt most 3. However, the accuracy of the measurements is unrealistic. For example, it is extremely unlikely that the distance travelled by a bike was measured to an accuracy of 1 millimetre! Although stopwatches display time intervals in hundredths of seconds, human response time is slower than that. So the measurements appear to have dubious precision and so should be treated with caution!
