Question
Ratio of speed of boat in downstream and speed of stream
is 5:2, if speed of current is 4 km/hr, then find distance travelled (in km) upstream in 6 hours.Solution
Let speed of downstream and speed of stream be 5x and 2x respectively. Speed of current => 2x = 4 => x = 2 km/hr Downstream speed = 5 × 2 = 10 km/h Speed of boat = 10 - 2 = 8 km/hr Upstream speed = 8 - 2 = 6 km/h Distance travelled upstream in 6 hr = 6 × 6 = 36 km
