Question

The distance between two ports is 750 km. Two ships start simultaneously from these ports towards each other. The speed of one ship is greater than the other ship by 30 km/hr. If the distance between two ships after 5 hours of their start is 80 km. Find the speed of each ship

Answer 1

Answer:

Step-by-step explanation:

Let the speed of one ship be x

Then the another ship be x+30

After 5 hours :

5x & 5(x+30)

5x-5x-150= 80

X= 150+80

x=230 km/h

Answer 2

Step-by-step explanation:

let X be the speed of one ship

y of second

X=y+30....(1)

distance traveled by one ship=x×5

distance traveled by second ship=y×5

5x+5y+80=750

5x+5y=670....(2)

5x+5y=670

+5x-5y=150

10x=520

X=52km/hr
