Issac and blaise decide to race. they both start at the same position at the same time. issac runs at 2m/s but decides to take a 2 minute rest stop along the way. blaise runs at half the speed and still wins by 10 m. how far did blaise run? show your work, it’ll greatly with my understanding. i know i have to do some substitution with equations, but i don’t have a final length of the race, or final time, so i have no idea where to start.

Let the Blaise runs for time "t" to complete the race

so the total distance he moved is given by

Now Issac runs for time t = "t - 2*60"

because it took rest for 2 minutes

now it is given that Blaise wins by 10 m distance

now the distance moved by Blaise is given by

d) physical means can be used to separate the components of air.

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
