suppose distance is x km
= speed in downstream = (3+1) km/ hr =4 km/ hr
= speed in upstream = (3-1) km / hr = 2 km/ hr
according to the question
time taken to go upstream + time taken to go downstream= 45/60
x/4 + x/2= 45/60= x= 1
thus the answer is (c)
give this the brainy answer.
hope this helps.
