Distance 55 m time 10.30 am and distance 255 m time 10.32 am. Find the avg. Speed.
Plz advice how total time is being calculated.
Divide change in distance by the change in time:
(255-55)/(10:32-10:30) = 200m/2min. = 100m/min. = 1.67m/s.
how do you get 1.67m/s
To find the average speed, we need to calculate the total time and total distance traveled.
Given:
First distance (d1) = 55 m
First time (t1) = 10:30 am
Second distance (d2) = 255 m
Second time (t2) = 10:32 am
To calculate the total time, we need to find the time difference between the two given times.
Total time = t2 - t1 = 10:32 am - 10:30 am
To calculate the time difference:
Step 1: Convert the given times into a common format (e.g., minutes).
10:30 am = 10 hours * 60 minutes/hour + 30 minutes = 630 minutes
10:32 am = 10 hours * 60 minutes/hour + 32 minutes = 632 minutes
Step 2: Calculate the time difference.
Total time = 632 minutes - 630 minutes = 2 minutes
Now, we can calculate the average speed.
Average speed = Total distance / Total time
Total distance = d1 + d2 = 55 m + 255 m = 310 m
Average speed = 310 m / 2 minutes
Therefore, the average speed is 155 m/min.
To calculate the average speed, we need to find the total time taken and the total distance covered.
In this scenario, we have two different distances and the respective times at which they were covered.
Given that the distance of 55 m was covered at 10.30 am and the distance of 255 m at 10.32 am, we can calculate the time taken to cover each distance.
The time taken to cover the first distance of 55 m is two minutes, from 10.30 am to 10.32 am.
Now, let's calculate the total time taken. Since the distance of 55 m was covered from 10.30 am to 10.32 am, and the distance of 255 m was covered at 10.32 am, we can consider the time from 10.30 am to 10.32 am as the total time taken.
Therefore, the total time taken in this case is 2 minutes.
Now, to find the average speed, we divide the total distance covered by the total time taken. The total distance is 310 m (55 m + 255 m), and the total time taken is 2 minutes.
Average Speed = Total Distance / Total Time taken
Average Speed = 310 m / 2 min
Hence, the average speed is 155 m/min.
