If atmospheric conditions are calm and stable (no moving air parcels), how much colder would you expect it to be at the top of Palomar Mountain compared to 1500m lower, near Escondido: For this question,
assume a dry adiabatic lapse rate (DALR) of 10C / 1000m, a saturated adiabatic lapse rate (SALR) of 7C / 1000m, and an environmental lapse rate (ELR) of 6C / 1000m

no simpler subs form complex ones. synthesise = make

when jerome paddle in flowing river towards east the net speed of jerome will increase

so the net speed of jerome will be given as

now the speed of paul will be same as it is given as he is running on the ground

so

so here we can say since the speed of jerome is more so he will win the race

now as we know the distance so the time difference is given as

so jerome will reach first and the time difference will be 203.55 s or 3.4 min
