Question

Vivek worked 35 hours and earned $385. At this rate, how many hours would it take him to earn $143?

Answer 1

Answer:

B. 13

Step-by-step explanation:

Time taken to earn $385 = 35 hours

Time taken to earn $1 = $\sf \dfrac{35}{385}$ hours

$\sf = \dfrac{1}{11} \ hours$

Time taken to earn $143 = $\sf \dfrac{1}{11} \times 143$ hours

$\sf = 13 \ hours$

Answer 2

35 divided by 385 is 11. This means Vivek will earn $143 in 11 hours.
