A crew of highway workers paved 2/15 mile in 20 minutes. If they work at the same rate, what portion of a mile will they pave in one hour?



Answer :

Divide [tex] \frac{2}{15} [/tex] by 20 to get how many miles the workers paved per minute. Remember that 20 = [tex] \frac{20}{1} [/tex]

[tex] \frac{2}{15} [/tex] ÷ [tex] \frac{20}{1} =[/tex] [tex] \frac{1}{150} [/tex]

The workers paves [tex] \frac{1}{150} [/tex] miles per minute

[tex] \frac{1}{150} * \frac{60}{1} = \frac{60}{150} = \frac{2}{5} [/tex]

The workers paved [tex] \frac{2}{5} [/tex] miles in 1 hour =)
