Carl and rick are traveling to a store 5 miles away. Carl is riding a bike, so he's going 12 mph faster than rick. If it takes rick 45 minutes, how long it take carl?

Therefore Carl takes  

Step-by-step explanation:

Speed : speed is the ratio of distance to time.

The S.I unit of speed = m/s

The C.G.S unit of speed = cm/s

12 mph means 12 miles per hour.

Let the speed of Carl be x.

Carl is going 12mph faster than Rick.

Then the speed of Rick is = (x-12)mph

We know that,

h

45 minutes = h

According to the problem,

We know that,

Therefore Carl takes
