Let the speed of car A = 15x km/h and the speed of car B = 19x km/h. Here the time is constant. According to question, => 19x – 15x = 16 => 4x = 16 => x = 4 Distance travelled by car B = 19 × 4 = 76 km
Speed of a boat in still water is 12 kmph and speed of stream is 6 kmph. A man rows to a place at a distance of 72 km and come back to starting point. T...
A man can row at 4 kmph in still water. If the velocity of current is 2 kmph and it takes him 5 hour to row to a place and come back, how far is the place?
Speed of boat is 10 km/hr. Speed of the stream is 20% less than speed of boat. Then find time taken by boat to go 54 km downstream?
A man can go on a motor boat with a speed of 15 km/hour in still water, he goes to a certain distance upstream and come back to the starting point in a ...
The ratio of the speed of the boat in upstream to that of in downstream is 2:3, respectively. If the speed of the current is 6 km/h, then find the speed...
A boy can swim a certain distance downstream in 3 hours and return in 8 hours. If the rate of stream is 5 kmph then what is the speed of boy in still wa...
A boat travels 42 km against the current and 72 km with the current in a total time of 8 hours. Additionally, it covers a distance of 56 km in still wat...
