Question
Ratio of speed of boat in downstream and speed of stream
is 7:5, if speed of current is 5 km/hr, then find distance travelled (in km) upstream in 4 hours. Section 4Solution
Let speed of downstream and speed of stream be 7x and 5x respectively. Speed of current => 5x = 5 => x = 1 km/hr Downstream speed = 7 × 1 = 7 km/h Speed of boat = 7 - 1 = 6 km/hr Upstream speed = 6 - 1 = 5 km/h Distance travelled upstream in 4 hr = 4 × 5 = 20 km
