Question

Tony bikes 7 miles in one hour. Predict how far he will bike in 4 hours

Answer 1

`\bf \begin{array}{ccll} miles&hours\\ \text{\textemdash\textemdash\textemdash}&\text{\textemdash\textemdash\textemdash}\\ 7&1\\ m&4 \end{array}\implies \cfrac{7}{m}=\cfrac{1}{4}\implies \cfrac{7\cdot 4}{1}=m`

Answer 2

7×4=28
so Tony will bike for roughly 28 miles in 4 hours
