Question

He covered a distance of 150 km in 5 hours at the end of his drive ,he returned back to where he started what was his average velocity for the trip

Answer 1

Answer

• Average speed is 10 km/h

Explanation

Given

• Distance travelled = 150 km
• Time = 5 hours
• He returns back to the initial place

To Find

• Average velocity?

Solution

Average Speed = Total Distance

━━━━━━━━━

Total Time

• So here we are given that the person goes once and comes back once so he covers a distance twice

Total Distance

➝ Total Distance = 150 + 150

➝ Total Distance = 300 km

Total Time

➝ Total Time = 5+5

➝ Total Time = 10 Hours

Average Speed

➝ Average Speed = Total Distance/Total Time

➝ Average Speed = 300/10

➝ Average Speed = 30 km/h
