Explanation Concept: When we move in the different mediums like air, water, treadmill or some other moving mediums then we need to combine rates. There can be two situations: I If we move in the same direction with medium then our rate will be added with the rate of the medium. I I If we move in the opposite direction of the moving medium then rates are subtracted. We generally consider our rate is greater than the rate of the medium to obtain a positive value. If we cover a certain distance in a given time then we can calculate the speed by using the following formulae: speed = d i s t a n c e t i m e We also know that, a b c = a b × c Calculation: Given that, a canoeist rows downstream in 1 1 2 hr and back upstream in 3 hr and he rows 9 miles in each direction. Then, Rate of the boat downstream = 9 3 2 m p h ⇒ R a t e o f t h e b o a t d o w n s t r e a m = 9 3 × 2 m p h Cancel the common factors ⇒ R a t e o f t h e b o a t d o

Units and Measurements

Measurements and comparisons are the foundation of science and engineering. We, therefore, need rules that tell us how things are measured and compared. For these measurements and comparisons, we perform certain experiments, and we will need the experime…
