Answer:
y=50x
Step-by-step explanation:
distance = 50 times the laps
100= 50 x 2
200 = 50 x 4
250= 50 x 5
400 = 50 x 8
Let the speed of the water current be v.
total travel time = time to go upstream + time to return downstream to the starting point
Hence, 8 = time in hours = 6 / (4-v) + 6 / (4 +v) = 6*8/(16-v^2)
Hence, 16 - v^2 = 6, or v^2 = 10 or v = √10 miles / hour
