Question

A road crew must repave a road that is 4/5 miles long. They can repave 1/20 miles each hour. How long will it take the crew to repave the road

Answer 1

Answer:

16 hours

Step-by-step explanation:

Total length of the road that needs to be repaved = $\[\frac{4}{5}\]$ miles

Total length of the road which is repaved by the road crew per hour = $\[\frac{1}{20}\]$ miles

Total number of hours required to repave the whole road = (Length of the road  to be repaved)/(Length of the road repaved by the crew per hour)

=$\[\frac{4}{5} \div \frac{1}{20}\]$

=$\[\frac{4}{5} * 20\]$

= 16 hours

Answer 2

Answer and Step-by-step explanation:

$Good~Day!$

$Let's~solve`your~equation!$

We know that:

→  $\frac{4}{5}~mi~and~\frac{1}{20}~mi~per~hour.$

→ $So,~multiply~\frac{4}{5}~by~a~number~that~will~give~your~denominator~(5)~to~20$

→ $5$ × $4~is~20,~multiply~\frac{4}{5}~by~4.$

→ $\frac{16}{20}~miles,~or~16~hours,~since~\frac{1}{20}~mi~is~made~per~hour.$

⇒ $So~16~hours~is~your~answer!$
