Question

The horse racing record for a 1.50 mi track is shared by two horses. Fiddle isle, who ran the race in 143 s on march 21, 1970, and john henry, who ran the same distance in an equal time on march 16, 1980. What were the horses' average speeds in:

a.Mi/s

Answer 1

we know that

the average speed is equal to

`average\ speed =(distance)/(time)`

in this problem we have

`distance=1.50\ miles\\ time=143\ seconds`

substitute the values in the formula

`average\ speed =(1.5)/(143)`

`average\ speed =0.01(miles)/(seconds)`
