Tony walks at an average speed of 70 m/min from his home to school. If the distance between his home and the school is
2100 m, how much time does it take for Tony to walk to
school?
min

The answer is 30 min

Explanation:

t = s/v

v = 70 m/min, s = 2100 m

t = 2100/70 = 30 min.

Hope it helps you! ＼(^ᴥ^)／

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

distance = 150m

displ = root (50 ^2 + 100^2)

root(2500+10000)

root 125000
