Answer 1

Answer:

John took 1 5/6 hours to clean the engine

Step-by-step explanation:

$time \: took \: to \: overhaul \: the \: engine = 5 \frac{1}{2}$

$5 \frac{1}{2} = \frac{2 \times 5 + 1}{2} = \frac{11}{2}$

$time \: took \: in \: cleaning = \frac{1}{3} of \: \frac{11}{2} hours$

$= \frac{1}{3} \times \frac{11}{2} hours \\ = \frac{1 \times 11}{3 \times 2}hours \\ = \frac{11}{6} hours = 1 \frac{5}{6} hours$

Therefore, John took 1 5/6 hours to clean the engine.
