A vehicle travels 200 metres in 5sec and then another 250 metres in 5sec. What is its average speed (in meters/sec)?
- A45
- B50
- C55
- D40
Solution & Step-by-step Explanation
The formula for average speed is:
Average Speed=
Total Time
Total Distance
Step 1: Find the total distance traveled
Total Distance=200m+250m=450m
Step 2: Find the total time taken
Total Time=5sec+5sec=10sec
Step 3: Calculate the average speed
Average Speed=
10
450
=45m/s
Average Speed=
Total Time
Total Distance
Step 1: Find the total distance traveled
Total Distance=200m+250m=450m
Step 2: Find the total time taken
Total Time=5sec+5sec=10sec
Step 3: Calculate the average speed
Average Speed=
10
450
=45m/s
