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

$average\ speed =\frac{distance}{time}$

in this problem we have

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

substitute the values in the formula

$average\ speed =\frac{1.5}{143}$

$average\ speed =0.01\frac{miles}{seconds}$
