How Long Is 180 Minutes
54 km in 180 minutes. How long does it take to fly 45 km with the same SD? 3
Because,
Distance = 54 kilometers = 54 x 10 meters
Time (t) = 180 minutes = 180 minutes x 60 seconds / 1 minute = 10800 seconds
SD (v) =?
We know this:
Sd (v) = distance (d) / time (t) = 54 x 10, m / 10,800 s = 5 m / s
Now how long will it take to travel 45 km with the same SD?
Distance (s) = 45km = 45 x 10, m
Sd (v) = 5 m / s
Time (t) =?
We know this:
Time (t) = distance (s) / sd (v) = 45 x 10, m / 5 m / s = 9 x 10, 3 seconds
Time (t) = 9 x 10³ seconds.
t = 180 * 45/54 = 180 * 5/6 = 30 * 5 = 150 minutes (150/60 = 2.50 hours)
180 minutes is 3 hours.
SD = 54 × 3 = 18 kilometers per hour
Let's use the following equation to make time in Urs.
d = v * t
45 = 18 * t
t = 45 × 18 = 2.5 ur
