Hey I am Ramandeep Singh. Do you want me to help you? Login Sign Up. Formula 1: If the ratio of downstream and upstream speeds is D: U, then ratio of time taken will be U : D. Question: A boat running upstream takes 8 hours 48 minutes to cover a certain distance, while it takes 4 hours to cover the same distance running downstream.
What is the ratio between the speed of the boat and speed of the water current respectively? Solution: When 8 hours 48 minutes is written using mixed fractions,. Therefore, the ratio of the time taken becomes Which on solving gives, Now, as the ratio of time is inversely proportional to that of Upstream and Downstream speeds.
Now, the ratio of speed of boat and the speed of stream will be. How far is the place? Solution: Take out the formula book. A man rows a certain distance downstream in X hrs and returns the same distance in Y hrs. Question: Ramesh can row a certain distance downstream in 6 hrs and returns the same distance in 9 hrs.
Formula 4: A man rows a certain distance downstream in X hrs and returns the same distance in Y hrs. Let us now jump to the questions, 1. A motorboat went the river for 14 km and then up the river for 9 km. If took a total of 5 hrs the entire journey. At his usual rowing rate, Rahul can travel 12 miles downstream in a certain river in 6 hrs less than it takes him to travel the same distance upstream.
But if he could double his usual rowing rate for this 24 mile round trip, the downstream 12 miles would then take only one hour less than the upstream 12 miles. What is the speed of the current in miles per hour? P, Q, R are three towns on a river which flows uniformly.
Q is equidistant from P and R. A man rows from P to Q and back in 10 hrs. He can row from P to R upstream in 4 hrs. The ratio of speed of man in still water to the speed of the current is:. How far is the place? Download success! Thank You, Your details have been submitted we will get back to you. Don't Miss An Update. Continue with Facebook. Forgot Password? Don't have an Account?
