Question

If a 162Km long road can be constructed in 9months. How many number of months are required to construct a 306km long road

Answer 1

Answer:

17 months

Step-by-step explanation:

time taken to construct 162 km road = 9 months

=> time taken to construct ( 162 / 162 ) km road = ( 9 / 162 ) months [ divide by 162 on both sides ]

so time taken to construct 1 km road = 1 / 18 months

time taken to construct ( 1 x 306 ) km road = ( 1/ 18 ) x 306 months [ multiply by 306 on both sides ]

so time taken to construct 306 km road = 306 / 18 = 17 months

So it takes 17 months to construct 306 km road
