Right Answer is:

SOLUTION

We know that 1000 m = 1 km

$∴ 1 m = \frac{1}{1000} k m$

$20 k m 50 m = 20 k m + 50 m = 20 k m + 1 m \times 50 = 20 k m + \frac{1}{1000} k m \times 50 = 20.050 k m$

$10 k m 200 m = 10 k m + 200 m = 10 k m + 1 m \times 200 = 10 k m + \frac{1}{1000} k m \times 200 = 10.200 k m$

Total distance travel = 20 km 50 m = 20.050 km

Distance travelled by bus = 10 km 200 m = 10.200 km

Distance travelled by auto = 20.050 –10.200

$\begin{matrix} Hundreds & Tens & Ones & . & Tenths & Hundredths & Thousandths 0 & 2 & 0 & . & 0 & 5 & 0 0 & 1 & 0 & . & 2 & 0 & 0 - 0 & 0 & 9 & . & 8 & 5 & 0 & = 9.850 \end{matrix}$

Therefore, distance travelled by auto = 9.850 km
