Question

Suppose you are driving to your vacation destination. You are driving at an average rate of 60 miles per hour. You must drive a total of 235 miles. If you had already driven 55 miles, how long will it take you to reach your destination?

Answer 1

`\begin{gathered} \text{speed}\Rightarrow60miles\text{ /hour} \\ \text{already driven=55 miles} \\ \text{total distance=235 miles} \\ \text{need to cover=235-55=180miles } \\ \text{time taken to complete the remaining distance is,} \\ t=(180)/(60)=3\text{ hour} \end{gathered}`
