Answer in units of s
How long to travel 12.4 km?
Answer in units of s
How long to travel 11 in?
Answer in units of s
thank you
1. d = Vt,
t = d / V = 210 / 433 = 0.485s.
2. t = 12400 / 433 = 28.6s.
3. d = 11in * (1/39.6)m/in = 0.278m,
t = d / V = 0.278 / 433 = 0.00064s.
To find the time it takes to travel a certain distance, you can use the formula:
Time = Distance / Speed
First, let's find the time it takes to travel 210 m:
Time = 210 m / 433 m/s = approximately 0.485 s
Next, let's find the time it takes to travel 12.4 km. We need to convert kilometers to meters to match the speed unit:
12.4 km = 12.4 * 1000 m = 12400 m
Time = 12400 m / 433 m/s = approximately 28.63 s
Lastly, let's find the time it takes to travel 11 inches. We need to convert inches to meters:
11 inches = 11 * 0.0254 m = 0.2794 m
Time = 0.2794 m / 433 m/s = approximately 0.0006 s
Therefore, the answers are:
1. It takes approximately 0.485 s to travel 210 m.
2. It takes approximately 28.63 s to travel 12.4 km.
3. It takes approximately 0.0006 s to travel 11 inches.
To find the time it takes for a jet to travel a certain distance, you can use the formula:
Time = Distance / Speed
Let's calculate the time for each scenario:
1. For the first question, the distance is given as 210 m and the speed is 433 m/s. Plugging these values into the formula:
Time = 210 m / 433 m/s
Simplifying:
Time = 0.485 s
Therefore, it takes approximately 0.485 seconds for the jet to travel 210 meters.
2. For the second question, the distance is given as 12.4 km, but the speed is still in meters per second. Since 1 kilometer equals 1000 meters, you'll need to convert the distance to meters before calculating the time:
12.4 km = 12.4 km x 1000 m/km = 12,400 m
Now, you can use the formula:
Time = 12,400 m / 433 m/s
Simplifying:
Time = 28.64 s
Therefore, it takes approximately 28.64 seconds for the jet to travel 12.4 kilometers.
3. For the third question, the distance is given as 11 inches, but the speed is still in meters per second. Since 1 inch equals 0.0254 meters, you'll need to convert the distance to meters before calculating the time:
11 inches = 11 inches x 0.0254 m/inch = 0.2794 m
Now, you can use the formula:
Time = 0.2794 m / 433 m/s
Simplifying:
Time = 0.000646 s
Therefore, it takes approximately 0.000646 seconds for the jet to travel 11 inches.
