In training for an Olympic bike race, Ped Al Moore trained by riding 216 miles in 12 hours, for an average of 18 miles per hour.

Answer:

$s=\frac{216}{t}$

Step-by-step explanation:

In training for an Olympic bike race, Ped Al Moore trained by riding 216 miles in 12 hours, for an average of 18 miles per hour.

Speed is inversely proportional to the time taken

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

speed is 18 miles per hour and distance is 216 miles

$18=\frac{216}{12}$

Let 's' be the speed and 't' be the different time

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

$s =\frac{distance}{t}$

Replace distance by 216

$s=\frac{216}{t}$
