Please solve question 6 fast

Dear Student,

Total length of highway = 500 km
Length of road constructed per day = 27.5 km
Length of road constructed in a week (that is, in 7 days) = 27.5 × 7 = 192.5 km
Therefore, length of road left to be constructed = ( 500 - 192.5 ) km = 307.5 km

Now, approximate number of days required to complete the construction of remaining length of the road (assuming that the construction continues at the same speed as the first week) = 307.5/27.5 = 11.18 days
So, approximate number of days will be around 11 days. 

Regards
