Ocean tides are waves that have a period of 12 hours, an amplitude (in some places) of 1.50 m, and a speed of 750 km/hr. what is the distance between adjacent crests of these waves?

distance between adjacent crests = 9000 km

Explanation:

given data

time period = 12 hours

amplitude = 1.50 m

speed = 750 km/hr

solution

we get here distance between adjacent crests that is express as

distance between adjacent crests = speed × time 1

put here value and we get

distance between adjacent crests = 750 × 12

distance between adjacent crests = 9000 km

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
