EXAMPLE To calculate average speed, divide the distance traveled by the elapsed time: averagespeed=titnedistancedistance=10hour550mileselapsedtime=10hoursaveragespeed=55mi:hr Directions Calculate the average specd. Write the answer on the line. 1. distance =120 millimeters 6. distance =12.5 millimetcis time =60 seconds time =0.5 seconds 2. distance =400 imeters: 7. distance =0.045 meters time =80 scconds. time =0.5 seconds 3. distaince =700 centimeters 8. distance =0.015millimeters timse =35 seconds time =0.10 seconds 4. distance =1,000 meters 9. distance =966 yards time =100 reconds. time =42 seconds 5. distance =175 miles 10. distance =396 kilometers time =5 hours time =6 hours Directions Read each word problem.
