Problema Solution
My house is 16 miles from my office. On Monday I traveled at 40 MPH for 15 minutes and at 30 MPH for 15 minutes. I was stopped for 2 minutes at stoplights. What was the magnitude of my average velocity in MPH?
Answer provided by our tutors
total time spent driving: 15+15+2 = 32 minutes
total distance: 16 miles
average velocity:
16 miles / (32/60) hours = 30
average velocity was 30mph
