Step-by-step explanation:
If v = 15 km/h We have:
d1 = 30 km
d2 = 17 km
Since speed = distance/time follows time = distance/speed.
The total time of the entire trip is is the sum of the time of the first 30 km and the time of the remaining 17 km:
d1/v + d2/(v + 2) = 30/15 + 17/(15 + 2) = 2 + 1 = 3 hours
The answer is t=3hours
