Question

Problem 2The driving distance between Portland, OR, and Seattle, WA is 174.2 miles. IfEddie is driving his old Volkswagen Bug at average speed of 69.5 miles perhour, and left Portland at 11:35 am, what time he will be Seattle?pm

Answer 1

The velocity is given by the expression:

`v=(d)/(t)`

where d is the distance and t is the time.

Plugging the values of the velocity and the distance we have:

`\begin{gathered} 69.5=(174.2)/(t) \\ t=(174.2)/(69.5) \\ t=2.5 \end{gathered}`

This means that it takes 2.5 hours to reach Seattle; this is the same as 2 hours 30 minutes. Adding this to the hour he left we have that:

`11\colon35+2\colon30=14\colon05_{}`

This means that Eddie reaches Seattle at 2:05 pm
