Question

How many hours will it take to complete a 76-km bike ride if you go 16 km per hour the whole time

Answer 1

so if you're going 16 kmh, that means in 1 hour, you do 16 km, thus


`\bf \begin{array}{ccll} km s&hour s\\ \text{\textemdash\textemdash\textemdash}&\text{\textemdash\textemdash\textemdash}\\ 16&1\\ 76&h \end{array}\implies \cfrac{16}{76}=\cfrac{1}{h}\implies h=\cfrac{76\cdot 1}{16}`

Answer 2

the correct answer is 4.75
