A boat goes downstream from one place to another in 9 hours. It covers the same distance upstream in 11 hours. If the speed of t
he stream is 2km/h, find the distance between 2 places? Please give answer with steps
1 answer:
Answer:
198 km
Step-by-step explanation:
The speed of the boat supposed to be x km/h
(x+2)*9 = (x-2)*11
9x + 18 = 11x – 22
2x = 40
X = 20
Distance between 2 places: (20 + 2) * 9 = 198 km
Or (20 – 2 ) * 11 = 198 km
