0.24 km - 0.06 km = 0.18 km
So he only paved 0.18 km a day.
In 12 days,
0.18 km x 12 = 2.16 km
He would have paved only 2.16 km
He still had 0.405 km of road not paved after 12 days. So he has 0.405 km more to pave.
Total length of road to pave
= 2.16 km + 0.405 km
= 2.565 km
See 1 Answer
Everyday, he pave 0.06km less than what was plan.
So,
1 day, he pave 0.24km - 0.06km = 0.18km
After 12 days, he would pave 2.16km
0.18 x 12 = 2.16km
Total length of road = amount he paved + amount unpaved
Total length of road = 2.16 + 0.405 = 2.565km
