If the speed of boat in still water is 20 km/hr & the speed of stream is 5 km/hr,then find Downstream speed and Upstream speed?
Downstream speed=25km/hr,
Upstream speed=15km/hr
Downstream speed=35km/hr,
Upstream speed=10km/hr
Downstream speed=30km/hr,
Upstream speed=10km/hr
Downstream speed=20km/hr,
Upstream speed=10km/hr
Explanation:
Speed of boat in still water = x = 20 km/hr
Speed of stream = y = 5 km/hr
Then,
Downstream speed=(20+5)=25km/hr
Upstream speed=(20-5)=15km/hr
