The circumference of a bicycle wheel is $15.4 \text{ dm}$ . If the wheel turned 50 times what distance did it cover in metres?

Identify the given values.
The circumference of the bicycle wheel is $15.4 \text{ dm}$ .
The wheel turned 50 times.
Calculate the total distance covered in decimetres.
The total distance is the circumference multiplied by the number of turns.
$\text{Total distance} = 15.4 \text{ dm} \times 50$ $\text{Total distance} = 770 \text{ dm}$
Convert the total distance from decimetres to metres.
We know that $1 \text{ dm} = 0.1 \text{ m}$ .
$\text{Total distance in metres} = 770 \text{ dm} \times \frac{0.1 \text{ m}}{1 \text{ dm}}$ $\text{Total distance in metres} = 77 \text{ m}$
The total distance covered by the bicycle wheel is $\text{77 m}$ .
