If it takes 42 minutes to load 3 1/2 trucks, how many minutes will it take to load 6 1/2 trucks?
If it takes 42 minutes to load 3 1/2 trucks, then it takes 42 / 3.5 = 12 minutes to load a single truck. By multiplying the number of minutes per truck by 6.5, we obtain the loading time. In this case, 12 x 6.5 = 78 minutes would be needed to load 6 1/2 trucks. The formula for the time taken is t = 12n, where t is the time in minutes and n is the number of trucks.

air exerts forces on objects that fall near the Earth’s surface. Explanation: The term “free fall” refers to objects falling towards the earth, in a situation where gravity is the only force acting on the object. for an object in free fall, the acceleration is constant (g, the gravitational acceleration), and therefore the speed of the object is constantly increasing. for objects close to the earth’s surface, there is always another force acting on the object: the resistance due to the air. this force is opposite to the direction of fall of the object and is proportional to the speed of the object, so that when the object falls, this force increases to a point where it balances the force of gravity and the object continues its movement at constant speed. (called terminal velocity). as in this case gravity is not the only force acting on the object, we are not in a situation of free fall.
