Question

A bicyclist ride 28 miles in 4 hours . At the same rate how many miles will she bicycle in 7 hours

Answer 1

Hello

To solve this question, we can easily equate both sides.

`\begin{gathered} 28\text{mi}=4hr \\ \text{xmi}=7hr \end{gathered}`

Cross multiply both sides and solve for x.

`\begin{gathered} 4* x=28*7 \\ 4x=196 \\ \text{divide both sides by the coefficient of x} \\ (4x)/(4)=(196)/(4) \\ x=49 \end{gathered}`

From the calculations above, she will cover 49 miles in 7 hours.
