On a windless day, a bird can fly at a constant 10 m/s. It flies 6.0km east and then home again.
How much time does the round trip take? I keep getting 600 seconds, but my teacher still tells me it's wrong.
time=distance/velocity= 12000m/10m/s=1200sec for the round trip.
1600 seconds
To determine the correct answer, let's break down the problem and calculate the round trip time step by step.
First, let's calculate the time it takes for the bird to fly 6.0 km east at a constant speed of 10 m/s. To do this, we can use the formula:
Time = Distance / Speed
Substituting the given values into the formula:
Time = 6.0 km / 10 m/s
To ensure that the units cancel out correctly, we need to convert the distance from kilometers to meters:
Time = (6.0 km * 1000 m/km) / 10 m/s
Simplifying this expression:
Time = 6000 m / 10 m/s
Time = 600 s
The time taken to fly 6.0 km east is indeed 600 seconds. Now, since the bird has to travel back to its starting point, we need to double this time to calculate the round trip time:
Round Trip Time = 2 * 600 s
Round Trip Time = 1200 s
Therefore, the correct round trip time is 1200 seconds, not 600 seconds as you initially thought. Double-check your calculations and make sure you have performed the steps correctly.
