Step-by-step explanation:
Let the speed of the boat be x km/hr
So, distance travelled be first boat in 2 hr = 2 × x = 2x
Since speed of other boat is 5 km/hr slower than the first boat
•°• The speed of the boat = (x-5) km/hr
So, distance travelled by first boat in 2 hr = 2(x-5)
=> Total distance= 2x + 2(x-5)
=> 110 = 2x + 2x - 10
=> 110 = 4x -10
=> 110 + 10 = 4x
=> 120 = 4x
=> x = 120/4
=> x = 30 km/hr
So here, We got the value of x as 30 km/hr
Hence the Speed of first boat is 30 km/hr & other boat is (x-5)
= (30-5)
= 25 km/hr
