Question
A man can row upstream at 24 km/hr. And downstream at 30 km/hr. Find the speed of the current.7 km/hr.3 km/hr.9 km/hr.6 km/hr
Solution
The speed of the current can be found by taking the difference of the downstream and upstream speeds and dividing by 2.
Here's the step-by-step solution:
- First, find the difference between the downstream and upstream speeds: 30 km/hr - 24 km/hr = 6 km/hr.
- Then, divide this difference by 2 to find the speed of the current: 6 km/hr ÷ 2 = 3 km/hr.
So, the speed of the current is 3 km/hr.
