Question

Alex excersice for $4\frac{1}{3}$ hours daily by running and doing yoga. He devotes $2\frac{3}{5}$ hours of his time for yoga. How much time does he devote for running?

• A. $1\frac{1}{15}$
• B. $3\frac{11}{15}$
• C. $2\frac{11}{15}$
• D. $1\frac{11}{15}$

Answer 1

The correct option is D $1\frac{11}{15}$

Total time of excersice = $4\frac{1}{3}=\frac{13}{3}$ hours

Time for yoga
= $2\frac{3}{5}=\frac{13}{5}$ hours

Thus, time devoted for running
= $\frac{13}{3}-\frac{13}{5}$

= $\frac{13\times 5}{15}-\frac{13\times 3}{15}$

= $\frac{26}{15}$

= $1\frac{11}{15}$
