d=156.8 m correct to 1 decimal place
d = 156.8 \text{ m correct to 1 decimal place}
d=156.8 m correct to 1 decimal places=24.2 m/s correct to 3 significant figures
s = 24.2 \text{ m/s correct to 3 significant figures}
s=24.2 m/s correct to 3 significant figuress=dt
s = \frac{d}{t}
s=td
sss = speed, ddd = distance, ttt = time
By considering bounds, work out the value of t t\,t to a suitable degree of accuracy.
