Q:

Alicia can row 6 miles downstream in the same time it takes her to row 4 miles upstream. She rows downstream 3miles/hour faster than she rows upstream. Find Alicia’s rowing rate each way. Round your answers to the nearest tenth, if necessary.a. 4 mi/h downstream, 2.7 mi/h upstreamb. 20 mi/h downstream, 13.3 mi/h upstreamc. 2.7 mi/h downstream, 4 mi/h upstreamd. 9 mi/h downstream, 6 mi/h upstream

Accepted Solution

A:
Answer: d. 9 mi/h downstream, 6 mi/h upstreamStep-by-step explanation:Hi, the correct answer is option d.d. 9 mi/h downstream, 6 mi/h upstream.We have to analyze the information given: "She rows  downstream  3  miles/hour faster than she rows upstream."So, with this information we have to choose the option that has the difference of 3 miles perhour between the downstream speed and the upstream speed. 9mi/h-6mi/h = 3mi/hOr, we can calculate it :x= upstream rowing rate6/ (x+3) = 4/x6x = 4 (x+3)6x =4x+126x-4x= 122x =12x=12/2x=6mi/h =upstream rowing rate.by adding 3mi/h, we obtain the downstream rowing rate:6mi/h + 3mi/h = 9mi/h downstream rowing rate.
