have a great day!!

for finding whether it is in inverse or direct proportion, always see if one quantity increases the other decreases incase of inverse proportion.

like in the first one, if 5 people take 28 days but we have to finish it early so the number of workers should increase to finish it in a less span of time. hence it's in inverse proportion as the number of men increase and the number of days decrease.

in Direct proportion, both the quantities increase or decrease.

like in the second if the train is moving in uniform speed, then time increases then distance increases
