Define direct, inverse and joint variation. Direct Variation: where one variable is a constant multiple of another Inverse Variation: when one of the variables increases, the other one decreases

Joint Variation: where are more than two variables are related directly define direct, inverse and joint variation

answer is c

explanation:

moving ball hits still ball. mover stops, hit ball moves. momentum transfer.

layers of the earth affect the waves and these effects are seen on instruiments such as seimometers

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
