Question

jonsi jogs from one and a to the other end B of a straight line 300m road in 2 minutes 50 seconds and then turn around and Fox 100 M back to. See in another one minute what are jerseys average speed and velocity in jogging

Find only A to C.

Answer 1

$\textbf{For finding A to C we have to find A to B}$

Total distance = 300 m.
Total time = 2 mins 30 s = 150 s.

Average speed = $\dfrac{Total\: distance}{Total\:time}$

= $\dfrac{300}{150}$


$\underline\bold{From\:A\:to\:c}$

Total distance = AB + BC .

= 300 m + 100 m.

= 400 m.

TOTAL TIME TAKEN = 2 min 30 s + 1 min.
= 210 s.

FORMULA OF AVERAGE SPEED = $\dfrac{Total\: distance}{Total\:time}$

= $\dfrac{400m}{210s}$

TOTAL DISPLACEMENT = Length CA

= AB - BC

= 300 m - 100 m

= 200 m

TOTAL TIME = 210s.

AVERAGE VELOCITY = $\dfrac{Displacement}{time}$

= $\dfrac{200m}{210s}$ along CA.

= 0.95 ms

Answer 2

1. Total distance = 300 m.
2. Total time = 2 mins 30 s = 150 s.
4. Average speed = \dfrac{Total\: distance}{Total\:time}
5. Totaltime
6. Totaldistance
10. = \dfrac{300}{150}
11. 150
12. 300
17. \underline\bold{From\:A\:to\:c}
18. FromAtoc
22. Total distance = AB + BC .
24. = 300 m + 100 m.
26. = 400 m.
28. TOTAL TIME TAKEN = 2 min 30 s + 1 min.
29. = 210 s.
31. FORMULA OF AVERAGE SPEED = \dfrac{Total\: distance}{Total\:time}
32. Totaltime
33. Totaldistance
37. = \dfrac{400m}{210s}
38. 210s
39. 400m
43. TOTAL DISPLACEMENT = Length CA
45. = AB - BC
47. = 300 m - 100 m
49. = 200 m
51. TOTAL TIME = 210s.
53. AVERAGE VELOCITY = \dfrac{Displacement}{time}
54. time
55. Displacement
59. = \dfrac{200m}{210s}
60. 210s
61. 200m
63. along CA.
65. = 0.95 ms
