In still water, Maria can paddle at the rate of 7 km/h. The current in which she paddles a speedof 4 km/h.At what valocity does she travel downstream? has
7km/h downstream
PLUS
4km/h downstream
7+4=11km/h downstream
To find the velocity at which Maria travels downstream, we need to consider the combined effect of Maria's paddling speed and the current.
Given:
Maria's paddling speed in still water = 7 km/h
Speed of the current = 4 km/h
When Maria paddles downstream, her speed is increased by the speed of the current since the current is flowing in the same direction. Therefore, to find the velocity at which she travels downstream, we add her paddling speed and the speed of the current.
Velocity downstream = Maria's paddling speed + Speed of the current
Velocity downstream = 7 km/h + 4 km/h
Velocity downstream = 11 km/h
Therefore, Maria travels downstream at a velocity of 11 km/h.
To determine Maria's velocity downstream, you need to consider the combined effect of the still water velocity and the current.
Velocity downstream can be calculated using the formula:
Velocity downstream = Maria's velocity in still water + Current velocity
In this case, Maria's velocity in still water is 7 km/h and the current velocity is 4 km/h.
So, to calculate Maria's velocity downstream, you simply add the two velocities together:
Velocity downstream = 7 km/h + 4 km/h
Therefore, Maria's velocity downstream is 11 km/h.
