In still water it takes him 3 hours to travel 30 miles.
That is 10 m/h
Going back it took him 6 hours which means he travelled at 5 m/h.
To slow him done by 5 m/h the current had to flow at 5 m/h

Hope this helps :)

Brand Number of Packets Cost
mash [69]

Brand 2 is the best value ⇒ B

Step-by-step explanation:

Let us write the Brand, Number of Packets and Cost

  • → Brand : Number of Packets : Cost
  • → 1          : 12                              : $10.68
  • → 2         : 16                              : $9.44
  • → 3         : 18                              : $15.30
  • → 4         : 24                             : $21.84
  • → 5         : 30                             : $20.40

We need to find what brand is the best value

To find that let us find the price of each packet in each brand, by dividing the price of the brand by the number of the packets, the cheapest price is the best

∵ Brand 1 has 12 packets

∵ The price of Brand 1 is $10.68

∴ The price of each packet = 10.68 ÷ 12 = 0.89

∴ The price of each packet in Brand 1 is $0.89

∵ Brand 2 has 16 packets

∵ The price of Brand 2 is $9.44

∴ The price of each packet = 9.44 ÷ 16 = 0.59

∴ The price of each packet in Brand 2 is $0.59

∵ Brand 3 has 18 packets

∵ The price of Brand 3 is $15.30

∴ The price of each packet = 15.30 ÷ 18 = 0.85

∴ The price of each packet in Brand 3 is $0.85

∵ Brand 4 has 24 packets

∵ The price of Brand 4 is $21.84

∴ The price of each packet = 21.84 ÷ 24 = 0.91

∴ The price of each packet in Brand 4 is $0.91

∵ Brand 5 has 30 packets

∵ The price of Brand 5 is $20.40

∴ The price of each packet = 20.40 ÷ 30 = 0.68

∴ The price of each packet in Brand 5 is $0.68

∵ The least price of a packet is in Brand 2

∴ The cheapest price is Brand 2

Brand 2 is the best value

A marine biologist will collect data regarding the length and weight of each of 50 trout caught and released at five different l
Vesnalui [34]
I think that the best visual representation that the marine biologist would use is utilising a bar graph. A bar graph is composed of bars residing in a coordinate plane. In addition to that, the visual representation would most likely be used since the average weight and length of each trout coming from 5 different locations is compared.
