The freeway blues! When you normally drive the freeway between Sacramento and San Francisco at an average speed of $105 \mathrm{km} / \mathrm{hr}(65 \mathrm{mph}),$ the trip takes 1.0 $\mathrm{hr}$ and 20 min. On a Friday afternoon, however, heavy traffic slows you down to an average of 70 $\mathrm{km} / \mathrm{hr}(43 \mathrm{mph})$ for the same distance. How much longer does the trip take on Friday than on the other days?

$=40 \mathrm{min}$

So we will start with using the normal driving time tto find the distance so distance tell X will be the average X times 20 on DH. We average minutes given Toby 105 kilometer art and time is one point Treat three hours so this distance is equal to 1 40 kilometer. Now we can use this distance to find the time on Friday, so we'll use the same question. But we will solve it for Delta T. Now we have dealt in. Toby called tow the ex over average velocity and Alex is the one that we found out over here. On average, velocity is 70 kilometers are now. Now they use this a question and we solve it for Delta E and we find the time to be to us. So the increasing time is we quite do then thing for 70 kilometers. But are mine still being for velocity that we could do 105 killings and this is equal to 0.67 Asked if you convert it into a minister after multi played by fact that off 16 on DH will get cancer will be 40 minutes
