Explanation:
It is given that,
A car travels 14 km due west, then does a U-turn and travels 43 km due east (when it takes U-turn, it will change direction from west to east)
i. Total distance = total path covered
= 14 km + 43 km
= 57 km
ii. Let east is positive and west is negative.
Displacement = final position-initial position
= 43-14
= 29 km
iii. If time taken in the entire trip = 3.2 hours
Average speed = distance/time
1 km/h = 0.2777 m/s
17.81 km/h = 4.94 m/s
iv. If time taken in the entire trip = 2.5 hours
Average velocity = displacement/time
1 km/h = 0.621 mph
11.6 km/h = 7.2 mph
Henc, this is the required solution.

Bacterial growth in human body is different from bacterial growth on the agar in a petri dish.
Explanation:
We know that in the human body there is the immune system which will interrupt the bacterial growth as they will be recognized as a foreign body and will be destroyed by employing immunological pathways.
Whereas on the agar medium balanced nutrient, pH, salts, amino acids and optimum temperature is provided for the bacterial growth. The desired conditions would be favorable for the growth of bacteria.
