The average speed for the entire journey is given by: Average Speed = Total Distance / Total Time The total distance traveled is: 50 + 80 = 130 km Time taken for the first part of the journey: Time = Distance / Speed = 50 / 25 = 2 hours Time taken for the second part of the journey: Time = Distance / Speed = 80 / 40 = 2 hours Total time = 2 + 2 = 4 hours Now, calculate the average speed: Average Speed = 130 / 4 = 32.5 km/h Correct Option: b) 32 km/h
49.97% of 2016 – 37.99% of 1050 = ? – 47.98% of 5950
24.89% of 720.01 - 4.09 × ? = (5.89)2
? 3 + 95.06 X 39.87 ÷ 5.03 = 1271.89
(29.97%) of 9840 + ? + (45.17% of 1240) = (31.955% of 11750)
13.96% of (141.17 + 158.85) + 7.95³ - (6.88 of 9.07) = ? of (58.06 - 13.02)
54.97% of 620.08 + 16.13 × 11.11 – 829.91 ÷ 5 = ?
15.1 + 3.97 – 9.07 × 1.96 = √?
124% of 620.99 + 11.65% of 1279.23 = ?
[{(√785) % of 449.85}/(35.89 × 7.14 + 849.89 ÷ 5.12 + 199.78% of 41.09)] = ( 1/? )
