Please help! How long would it take (in seconds) to travel 1 km at a speed of 100 km/h?
D = V*t, so
t = D/V
Convert the answer (1/100 hour) to seconds, if you wish.
36 seconds
To calculate how long it would take to travel 1 km at a speed of 100 km/h, you can use the formula:
Time = Distance / Speed
In this case, the distance is 1 km and the speed is 100 km/h. Substituting these values into the formula, we get:
Time = 1 km / 100 km/h
To proceed with the calculation, we need to convert the speed from kilometers per hour (km/h) to meters per second (m/s), as the distance is given in meters.
To do that, we need to remember that 1 kilometer is equal to 1,000 meters, and 1 hour is equal to 3,600 seconds.
So, 100 km/h is equal to (100 * 1,000) meters / (1 * 3,600) seconds, which simplifies to:
100,000 meters / 3,600 seconds
Now, we can go back to our initial formula:
Time = 1 km / (100,000 m / 3,600 s)
Dividing 1 km by (100,000 m / 3,600 s) gives us:
Time = (1 * 3,600 s) / 100,000 m
Simplifying further, we have:
Time = 3,600 s / 100,000 m
Dividing 3,600 by 100,000 gives us:
Time ≈ 0.036 seconds
Therefore, it would take approximately 0.036 seconds to travel 1 km at a speed of 100 km/h.
