1.) A bird can fly 20 km/h. How long does it take to fly 12 km?
2.) If you are driving 116 km/h along a straight road and you look to the side for 3.0 s, how far do you travel during this inattentive period?
1. d = r * t = 12 km.
20 * t = 12
t = 0.6 h.
2. r = 116km/h = 116000m/3600s=32.22m/s.
d = r * t = 32.22m/s * 3s = 96.7 m.
To find the answer to the first question, you can use the formula: time = distance / speed. Plugging in the given values, the calculation should be: time = 12 km / 20 km/h.
To solve this, divide 12 km by 20 km/h:
time = 0.6 hours or 36 minutes.
Therefore, it would take the bird 0.6 hours or 36 minutes to fly 12 km.
For the second question, to find the distance traveled during the inattentive period, multiply the speed by the time. Using the formula: distance = speed * time, insert the provided values: distance = 116 km/h * 3.0 s.
First, convert seconds to hours by dividing by 3600 (since there are 60 seconds in a minute and 60 minutes in an hour).
3.0 seconds / 3600 = 0.0008333 hours.
Now multiply the speed of 116 km/h by the converted time of 0.0008333 hours:
distance = 116 km/h * 0.0008333 hours.
The result of this calculation is approximately 0.097 km or 97 meters.
Therefore, while looking to the side for 3.0 seconds at a speed of 116 km/h, you would travel approximately 0.097 km or 97 meters.
