Speed of boat downstream
= Distance coveredTime taken=302Distance coveredTime taken=302 = 15 km/h
Now, speed of boat upstream
= Distance coveredTime taken=306Distance coveredTime taken=306 = 5 km/h
Now, speed of boat
= Speed downstream+Speed upstream2Speed downstream+Speed upstream2
= 15+52=20215+52=202 = 10 km/h
= Distance coveredTime taken=302Distance coveredTime taken=302 = 15 km/h
Now, speed of boat upstream
= Distance coveredTime taken=306Distance coveredTime taken=306 = 5 km/h
Now, speed of boat
= Speed downstream+Speed upstream2Speed downstream+Speed upstream2
= 15+52=20215+52=202 = 10 km/h
