The plane can cover a distance of 1380 km in 2 hours and 18 minutes if it flies with a constant speed of 600 km/h.
This is an exercise of the uniform rectilinear movement (MRU) is a type of movement in a straight line in which an object moves with constant speed. The MRU is one of the simplest movements to analyze and is used as a mathematical model to understand more complex movements.
The MRU is an important motion in physics, as it is a basic example of motion in a straight line with constant velocity. Also, many movements in real life can be approximated by the MRU.
The formula that defines the MRU is:
V = d/t
Where
- V = velocity
- d = distance
- t = time
We are told that the plane flies at a speed of 600 km/h, and we are asked how far it travels in 2 hours and 18 minutes.
Before proceeding, calculate the hours and minutes, then
t = 2 h = 120 min + 18 min = 138 min/60 h = 2.3 h
Now we have our complete data, we clear the formula for the distance and solve, then
d = v × t
d = 600 km/h × 2.3 h
d = 1380 km
The plane can cover a distance of 1380 km in 2 hours and 18 minutes if it flies with a constant speed of 600 km/h.
