It takes you 15 minutes to drive 6.0 miles in a straight line to the local hospital. It takes 10 minutes to go the last 3.0 mile
s, 2.0 minutes to go the last mile, and only 30 seconds (= 0.50 minutes) to go the last 0.50 miles. What is your average velocity for the trip? Take the positive xx direction to be from your starting point toward the hospital.
The overall trip is 15 min for the 6 miles. Plugging that into the equation for Average velocity you get 6m/15min. The answer is asking for m/h. So we know there are 60 minutes in 1 hour. You cross multiply 6m/15min with 60min/1h and get 360m/15h and can reduce it to 24m/h.
Blood pressure. It’s one of the most important measurements in medicine. And yet, taking it correctly is kind of an art. It’s fluid, it changes, and it can be impacted by something as simple as being at the doctors’ office.
