Question

Укладчик укладывает в день 168 м асфальта. В какой по счету день после начала работ он закончит укладку пути длиной: а) 2км; б) 9км; в) 25 км; г) 1 км700м⇔⇔

Answer 1

A)   2 000 :168 = 11 ( остаток 152)  - на 12 день
б)   9 000 : 168 =  53 ( остаток 96) - на 54 день
в)   25 000 : 168 = 148 (36) - на 149 день
г) 1700 : 168 = 10 (остаток 20) - на 11 день

Answer 2

Calculation of Days to Complete Asphalt Paving

To determine the number of days it will take for the asphalt paver to complete the road, we need to calculate the number of meters of asphalt that can be laid in a day and then divide the total length of the road by that value.

Given that the asphalt paver can lay 168 meters of asphalt in a day, we can calculate the number of days it will take to complete the road for each given length:

a) For a road length of 2 km (2000 meters), the number of days required would be: 2000 meters / 168 meters per day = 11.90 days. Since we cannot have a fraction of a day, we round up to the nearest whole number. Therefore, it would take approximately 12 days to complete the road.

b) For a road length of 9 km (9000 meters), the number of days required would be: 9000 meters / 168 meters per day = 53.57 days. Rounding up to the nearest whole number, it would take approximately 54 days to complete the road.

c) For a road length of 25 km (25000 meters), the number of days required would be: 25000 meters / 168 meters per day = 148.81 days. Rounding up to the nearest whole number, it would take approximately 149 days to complete the road.

d) For a road length of 1 km 700 m (1700 meters), the number of days required would be: 1700 meters / 168 meters per day = 10.12 days. Rounding up to the nearest whole number, it would take approximately 11 days to complete the road.

Please note that these calculations assume that the asphalt paver can consistently lay 168 meters of asphalt per day without any interruptions or delays.
