Formula used: When distance is equal, Average speed = [2 × S1 × S2] / [S1 + S2] Calculation: Average speed = (2 × 3 × 6)/ (3 + 6) ⇒ 36 / 9.
2 dni temu · Average Speed Question 1 Detailed Solution. Given: Speeds on the triangular plane = 12 kmph, 18 kmph, and 36 kmph. Formula Used: Average Speed = Total Distance / Total Time. Calculation: Let the side of the equilateral triangle be d km. Time taken for the first side = d / 12. Time taken for the second side = d / 18.
3 dni temu · Let's solve the problem step by step. Step 1: Find the speed of the faster train. Given, the faster train crosses a lamp post in 12 seconds, and it is 160 m long. So, the speed of the faster train (V f) is: Vf = \frac {Distance} {Time} V f = T imeDistance = \frac {160m} {12s} = 13.33 \text { m/s} 12s160m = 13.33 m/s.
