Answer:
The given speed of the motor boat in the still water is equal to 18 km/hr. The given distance travelled by motor boat is equal to 24 km. The time taken to travel 24 km downstream bymotor boat = 1 hour. x=122=6km/hr.
The given speed of the motor boat in the still water is equal to 18 km/hr. The given distance travelled by motor boat is equal to 24 km. The time taken to travel 24 km downstream by motor boat = 1 hour. x=122=6km/hr.

Answer:
The given speed of the motor boat in the still water is equal to 18 km/hr. The given distance travelled by motor boat is equal to 24 km. The time taken to travel 24 km downstream by motor boat = 1 hour. x=122=6km/hr.
Step-by-step explanation:
Given:-
Speed of boat =18km/hr
Distance =24km
Let x be the speed of stream.
Let t
1
and t
2
be the time for upstream and downstream.
As we know that,
speed=
time
distance
⇒time=
speed
distance
For upstream,
Speed =(18−x)km/hr
Distance =24km
Time =t
1
Therefore,
t
1
=
18−x
