GB-29-01-001 · Average speed

A cyclist travels 33 km in 65 minutes. Calculate the average speed in km/h, to 1 decimal place.

Speed, Distance, Time ("DuSTy" Table) Booklet p. 54

Method

1) Convert minutes to hours (÷

2) Draw DuSTy table (S | D | T) and use S = D ÷ T

Worked Example (GB-29-01-001)

1) Convert minutes to hours:

65 \div 60 = 1.0833\dots\text{ hrs}

Journey	S (Speed)	D (Distance)	T (Time)
Cyclist	$S = 33 \div \frac{65}{60}$	$33\text{ km}$	$\frac{65}{60}\text{ h}$

30.5 km/h
