A boat covered 5/9 of a journey at an average speed of 25 mph then it travels remaining 120 miles at another speed if the total time of the whole journey was 8 1/2 hours what was the amount of time the boat spent on the remaining 120 miles? (write as a decimal)

its a 5.5 n

glad that

continuous conducting path for current, power supply

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
