Step-by-step explanation:
Length of the road = 2.5 km = 2500 m ( 2.5 × 1000 )
Work done on day 1 = 1/4 of the total work
= 1/4 × 2500
= 625 m
Work done on day 2 = 1375 m (given)
Work done on day 3 = 625 + 1375 = 2000
= 2500 - 2000
= 500 m
---------------------------------------------------------------------------------------------------------
(a) Length of the road completed till day 2 = day 1 + day 2
= 625 m + 1375 m
= 2000m
= 2 km (2000 ÷ 1000)
(b) Maximum work was completed on day 2 ( day 3 < day 1 < day 2 )
( 500 m < 625 m < 1375 m )
