Question

a man con row 40 km upstreama and 55 km dowstream in 13 hours .also he con row 30 km upstrem and 44 km doewnstream in 10 hours. find the speed of the man in stil water and the speed of the current​

Answer 1

Answer:

hey mate you can change your values in this solution

hope it helps

Step-by-step explanation:

Let rate upstream = x kmph & rate downstream = y kmph

Let rate upstream = x kmph & rate downstream = y kmphThen 30/x + 44/y = 10

Let rate upstream = x kmph & rate downstream = y kmphThen 30/x + 44/y = 10 and 40/x + 55/y = 13

Let rate upstream = x kmph & rate downstream = y kmphThen 30/x + 44/y = 10 and 40/x + 55/y = 13 On solving we get x = 5 and y = 11

Let rate upstream = x kmph & rate downstream = y kmphThen 30/x + 44/y = 10 and 40/x + 55/y = 13 On solving we get x = 5 and y = 11So, rate upstream = 5 km/hr and rate downstream = 11 km/hr

Let rate upstream = x kmph & rate downstream = y kmphThen 30/x + 44/y = 10 and 40/x + 55/y = 13 On solving we get x = 5 and y = 11So, rate upstream = 5 km/hr and rate downstream = 11 km/hrRate of current = 1/2(11-5) km/hr = 3 km/hr

Let rate upstream = x kmph & rate downstream = y kmphThen 30/x + 44/y = 10 and 40/x + 55/y = 13 On solving we get x = 5 and y = 11So, rate upstream = 5 km/hr and rate downstream = 11 km/hrRate of current = 1/2(11-5) km/hr = 3 km/hrRate in still water = 1/2(11+5) km/hr = 8 km/hr
