Question

A company can repair 2whole1/5 km of road in a day. How many days will it take to repair a road 24 whole 3/5km long.
​

Answer 1

Answer:

Length of road that can be fixed in 1 day = $2 \frac{1}{5} \: km = \frac{11}{5} \: km$

Length of road that can be fixed in 'x' days = $24 \frac{3}{5} \: km = \frac{123}{5} \: km$

No. of days (Value of 'x')

$= \frac{123}{5} \div \frac{11}{5} \\ = \frac{123}{5} \times \frac{5}{11} \\ = \frac{123}{11} \\ = 11 \frac{2}{11} \: days$

Answer 2

Answer:

11+2/11 days

Explanation:

given : total work = 24+3/5 km

per day work = 2+1/5 km

therefore no of days = (24+ 3/5)km ÷ (2+1/5)km/day

= (24×5)+3 ÷ (2×5)+1

5 5

= 123 (since 5 got cancelled by each other)

11

= 11+2/11 days
