Answer 2

how is that helping me

Answer 3

ok so we have 3600 seconds in an hour (60^2) and google told me there's 5280 foot in a mile

Answer 4

ok im still confused

Answer 5

well, if he ran 300ft in 2.92 seconds than he ran 300/2.92 ft/s

so about 102.739726027 feet per second

Answer 6

i got that 2

Answer 7

i need miles per hour

Answer 8

102 feet is 0.019 mile or so (102/5280). so he runs about 0.019 mile per second

Answer 9

multiply that by 3600 and you get miles per hour

Answer 10

\[1 ~yard=3 ft,1~mile=1760 ~yards=1760 *3=5280~ft\]

Answer 11

oh i see what you did ok thanks

Answer 12

\[average~speed=\frac{ 300 ft }{ 2.92 \sec }=\frac{ \frac{ 300 }{ 5280 } }{ 2.92 }miles/\sec=\frac{ 300 }{ 5280 *2.92 }*3600 m/hr=?\]

Answer 13

i got it thanks guys
