Answer: The answer is s = d/tStep-by-step explanation:For question 12, I think this is called a literal equation, I might be wrong but I believe so it is a literal equation. They are asking you to get s on one side. And they are asking you what s is in terms of d and t. So what you do is, d = s x t. You multiply the t with the s and get d = st. Then you will divide t from both sides so, d/t = s/t, this will eliminate t from the s, and add it on to the d (distance). Which will leave you s on one side and d and t on the other. The answer is s = d/t.

S O L U T I O N :Section 3 12) a) Here, as we need that s or speed is the subject so speed should be in place of distance. So, we get s = d/tHere, s is speed, d is distance and t is the time 12) b) We know that : Average Speed = Total Distance/Total Time Here, total distance is given 748 km total time 11.5 hrs Avg. Speed = 748/11.5 Avg. Speed = 65.04 km/h Hence, the answer is 65.04 km/h13) a) We know that volume of a rabbit hutch is Volume of rabbit hutch = ½ × b × h × l Here, b is the breadth, h is the height and l is the length Volume= ½ × 50 cm × 50 cm × 2.5 m Now, here Length is in metre so we need to convert to cm 1 m = 100 cm 2.5 m = 2.5 × 100 = 250 cm So, nowVolume= ½ × 50 cm × 50 cm × 250 cm Volume = 50 cm × 50 cm × 125 cm Volume = 312,500 cm³ Hence, the volume of this hutch is 312,500 cm³13) b) Let us assume that the orange be a sphere So, volume of orange = 4/3πr³ Here, r is the radius and π is pi radius is 4 cm Volume = 4/3π(4)³ Volume = 4/3 × 64π Volume = 85.33π cm³ Volume of the orange is 85.33π cm³
