Question

I really need help with this and a really good and understandable explanation please it's not 0.54

Answer 1

`\stackrel{mixed}{9(1)/(2)}\implies \cfrac{9\cdot 2+1}{2}\implies \stackrel{improper}{\cfrac{19}{2}} \\\\[-0.35em] ~\dotfill\\\\ \cfrac{19in}{2s}\cdot \cfrac{ft}{12in}\cdot \cfrac{mi}{5280ft}\cdot \cfrac{60s}{min}\cdot \cfrac{60min}{hr}\implies \cfrac{19\cdot 60\cdot 60}{2\cdot 12\cdot 5280}\cfrac{mi}{hr} \\\\\\ \cfrac{68400}{126720}\implies \cfrac{95}{176} ~~ \approx ~~ 0.54 ~~ \approx ~~ \text{\LARGE 0.5}~(mi)/(hr)`
