Question 1172460: For the first 30 km, the bicyclist rode with a speed of v km/hr. For the remaining 17 km he rode with a speed which was 2 km/hour greater than his original speed. How much time did the bicyclist spend on the entire trip? Let t be the time in hours. Find t if v=15 km/hr, and also write t in terms of v.
I already found t if v=15 km/hour, I'm just struggling to write t in terms of v.

                SPEED    TIME       DISTANCE

First Part         v     30/v         30

Last Part         v+2    17/(v+2)     17

Entire                    t           47
