Answer:
57.26mph
Step-by-step explanation:
Speed= Distance Travelled ÷ Time Taken
Distance=0.028 miles
Time=1.76 seconds
To convert time from seconds to hour, we divide it 3600 because 1 minute is equal to 60 seconds and 1 hours is equal to 60 minutes so 60* 60= 3600 . Thus:
Time in hours = 1.76 ÷ 3600 = 0.000489 hours
Speed =0.028 ÷ 0.000489
Speed =57.26mph
