#### Question No 1

IF a catamaran travel at a speed of 20 km per hour in stillwater. So when it travel at a downstream speed 5 kilometre per hour. What will be the time taken by it to travel 90 km.

Solution!
Since the catamaran is travelling in downstream the speed of the stream as a pin the speed of the ship so its speed is equals to catamaran speed+downstream speed. Which becomes 20+5=25 km/he. Now by applying a formula we get
Time=90/25. We get our answer which is 3.6
