If each life preserver is 3 meters on either side, up and down, then you will reach either life preserver with the equal amount of time. As both you and the two life preservers are travelling downstream at equal speed. If you swim to the life preserver upstream you are effectively slowing yourself down and allowing the life preserver upstream to catch up to you. On the other hand, if you swim to the life preserver downstream you are effectively speeding yourself up to catch up to the life preserver downstream. As the frame of reference is the movement of the river, your distance to either life preserver is the same and hence can be reached with the equal amount of time. Answered by Ask4MyTutor
What else can I help you with?
Does a river flow from upstream to downstream?
No, a river only flows one way, they either flow upstream or downstream not both.
How do you replace the upstream and downstream Oxygen Sensor on a 2006 Chevy Equinox?
From underneath car there about 2' apart on either side of converter. Upstream is much harder then the downstream which is easy
What is the process in which water changes its potential energy to kinetic energy as it moves from upstream to downstream?
That means that the water either flows downstream, or falls down, depending on the case.
Riverboat with a stream powers engine that could travel up-or downstream?
A riverboat with a steam powered engine that could travel either upstream or downstream was called a steam boat.
How many O2 sensors are on a 2004 dodge durango?
4 sensors total. 2 upstream on either side of exhaust manifold, 1 left side downstream, 1 right side downstream.
Where is the o2 sensor on 98 ford mustang v6?
There are 2 or 3 oxygen sensors in your exhaust. "Upstream" sensors are located between the exhaust manifolds (headers) and the catalytic converter (usually located on the mid-pipe); "downstream" sensors are located after the catalytic converters. On V6 Mustangs there can either be one or two upstream sensors and usually only one downstream sensor.
What is partial vertical integration?
Partial vertical integration is the action in which a firm aquires control in either an upstream supplier or a downstream buyer with a share ratio of less than 100 % in the integrated firm.
How many oxygen sensors are on a '02 Taurus with a v6?
you have 2 O2 sensors, an upstream O2 sensors located in front of the catalytic converter and the downstream is behind it either on the exaust manifold or the exaust manifold pipe
Is your shut off upstream or downstream from your water meter?
Could be either or both. There is usually a cutoff between the meter and the main line, though it is usually located outside. And there is usually one near the outlet of the meter.
How many O2 sensors does a 2008 Honda Fit have?
The 2008 Honda Fit is equipped with two oxygen (O2) sensors: one upstream (pre-catalytic converter) and one downstream (post-catalytic converter). The upstream sensor helps monitor the air-fuel mixture, while the downstream sensor checks the efficiency of the catalytic converter. If either sensor fails, it can trigger a check engine light and affect vehicle performance.
Where are the oxygen sensors located on a ford probe 97 GT and how many are?
There are a total of four Oxygen Sensors: one in each exhaust manifold near the motor, and one on either side (upstream & downstream) of the catalytic converter.
Where are 02 sensors located on 99 merc villager and how hard are they too get out?
Actually, there are two O2 sensors. One upstream on the exhaust manifold and one downstream at the catalytic converter. Either should be tested before shot-in-the-dark replacement.
