Answer 2

All the cows plough 2.844 km in one day

Step-by-step explanation:

$100000 cm = 1 km$

1 Cow ploughs land in the morning = 7800cm = \frac{7800}{100000}=0.078 km

1 km = 1000 m

1 Cow ploughs land in the evening = 80 m = $\frac{80}{1000}=0.08 km$

Total ploughing done by 1 cow in 1 day = 0.078 km+0.08 km = 0.158  km

Total ploughing done by 18 cow in 1 day =$0.158 \times 18 = 2.844 km$

So, all the cows plough 2.844 km in one day
