An object travels 30 miles to the north, 15 miles to the west, and then another 15 miles to the north in 30 minutes. What is its speed in miles per hour?
+37091 Are you dealing with VECTORS and want to know the VELOCITY?
If you just want the SPEED it is Distance/Time = (30+15+15 miles) / (1/2 hr) = 60 / 1/2 = 120 MPH
