Astudent ran 100yd in 12 seconds. at what speed did the student run in mph

17.057 mph

Step-by-step explanation:

Speed= Distance Travelled ÷ Time Taken

As we know that: 1 yard = 0.000568 miles so

100 yard= 0.0568 miles

Time=12 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 = 12 ÷ 3600 = 0.00333 hour

Speed =0.0568 ÷ 0.00333

Speed= 17.057 miles per hour

2 seconds
