Question

Harry and his family travel 204 miles in 3.4 hours. If they continue at this constant speed, how long will it take them to travel 420 miles? Complete the ratio table.

Answer 1

Distance = 204miles

Time = 3.4

`\begin{gathered} 3.4hours\text{ = 204miles} \\ 1\text{hour = Y} \\ 3.4Y\text{ = 204} \\ Y\text{ =}(204)/(3.4)\text{ = 60 miles} \end{gathered}`
`\begin{gathered} 3.4hours\text{ = 204miles} \\ K\text{ hours = 420 miles} \\ By\text{ cross multiplying} \\ K\text{ X 204 = 420 X 3.4} \\ K\text{ =}(420*3.4)/(204)=(1428)/(204)=7\text{ hours} \end{gathered}`
