Jana's rode her bike 12 miles in 45 minutes, so Jana's rate per hour is 16 miles/hour.

Given that, Jana is training for a triathlon that includes a 112 mile bike ride.

What is the speed?

The speed formula can be defined as the rate at which an object covers some distance. Speed can be measured as the distance travelled by a body in a given period of time. The SI unit of speed is m/s.

Today she rode her bike 12 miles in 45 minutes.

Here, 45 minutes =45/60 =3/4

Speed =Distance/Time

= 12 ÷ 3/4

= 12 × 4/3

= 16 miles/hour

Therefore, Jana's rode her bike 12 miles in 45 minutes, so Jana's rate per hour is 16 miles/hour.
