Boats and Streams test 2

If man’s rate in still water is 10 km/hr and velocity of water  is 7 km/hr then how much distance does he traveled in down stream in 3      hrs?





If boat’s rate in still water is 15km/hr and current rate is 5 km/hr then how much time takes to travel 60 kms in down stream?





if boats rate in still water is 20 km/hr and stream rate is 11  km/hr then how much distance he traveled in upstream in 20 min?





if man’s rate in still water is 20 km/hr and current rate is 4  km/hr then how much time takes to travel 32 kms up stream?





If man’s rate in still water is 30 km/hr and stram rate is 10      km/hr then how much distance does it traveled in 15 mins in upstream?





If down stream speed is 10 km/hr and upstream speed is 4 km/hr  then find Man’s rate n still water?





If downstream speed is 20 km/hr and upstream sped is 4 km/hr then find currant rate?





If man’s rate in still water is 15 km/hr and current rate is 5 km/hr it takes 6 hrs to row to a place and back/ How far is the place?





If a distance of traveled is 18 kms and returns the same  distance in 10 hrs man’s rate in still water is 10 km/hr then find the velocity of water?





if a distance of 150 kms traveled and returned in 20 hrs stream rate is 10 km/hr then find boat’s rate in still water?
