Question

two boats are 110m apart. they travel towards each other one travelling 5km/h slower than other. if they meet after 2hrs ,find the speed of the boats

Answer 1

hoping it will be helpful

Answer 2

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
