If one mechanic can assemble a motor in 6 2/9 hours, while another mechanic can do the same job in 10 5/9 hours, how much more quickly can the first mechanic do the job?

[tex]6 \frac{2}{9} = \frac{56}{9} \\ 10 \frac{5}{9} = \frac{95}{9} [/tex]

[tex] \frac{95}{9} - \frac{56}{9} = \frac{39}{9} = \frac{13}{3} hours[/tex]
