A police car drives with a constant speed of 58 miles per how long will it take to travel a distance of 29 miles
1 answer:
Answer:
It takes 2 hours for a police car to travel a distance of 29 miles with 58 miles per hour.
Explanation:
The speed of the car is 58 miles per hour.
The total distance traveled is 29 miles.
We need to find the time taken to cover the distance of 29 miles by the police car if police traveled at 58 miles per hour.
We know that,
Relationship between speed, time and distance is
Now substitute the given values in the above formula,
Time = 2 hours.

Answer: Option (d) is the correct answer.
Explanation:
Steps involved for the given reaction will be as follows.
Step 1: (fast)
Rate expression for step 1 is as follows.
Rate = k
Step 2:
This step 2 is a slow step. Hence, it is a rate determining step.
Step 3. (fast)
Here, is intermediate in nature.
All the steps are bimolecular and it is a second order reaction. Also, there is no catalyst present in this reaction.
Thus, we can conclude that the statement step 1 is the rate determining step, concerning this mechanism is not directly supported by the information provided.
