Question

One boat travels 10kph faster than another. While one boat travels 125 km, the other travels 155 km. Find their speed.

Answer 1

Answer:

the speed of the more speedy boat is 51.67km/h

and another is 41.67km/h.

Answer 2

Answer: The answer to this question is 51.67kph and 41.67kph respectively.

Step-by-step explanation:

We had been given the following details that there are two boats and one of them has a speed 10kph more than that of the other one

and it had been given that if boat1 moves a distance d1.

and boat2 moves a distance d2.

Let the v1 be the velocity of boat 1

Let the v2 be the velocity of the bat 2

I am using one more concept which is about how to write distance in terms of velocity and time which you can see in line number 3.

More or less the basic trick of the question was to calculate the time, if you had cracked it then you will get it correct.

$v2-v1=10\\d2-d1=155-125=30\\(v2-v1)t= 30\\\\t=3\\v2(t)=155\\v2= 155/3\\ =51.67kpph\\v1= 125/3\\= 41.67kph$
