The cyclist

The cyclist went from village to town. First half of journey went at 20 km/h. The second half of the journey, which mostly fell, went at 39 km/h. All journey took 88 minutes. Calculate the distance from the village to the town.

Correct result:

d =  38.8 km

Solution:

20t1=39t2 t1+t2=8860 t10.97 h t20.5 h s=20t1+39t2=38.8 km
