Rahul drove his bike for 2 hours at 60 km/h and 3 hours at 70 km/h. Calculate average velocity.
Answers
Answer:
26km/hr
Explanation:
Rahul drove his bike for 2 hrs at 60 km/hr.
Rahul drove his bike for 3 hrs at 70 km/hr.
⁂ total time Rahul drove for = (2 + 3) hr = 5 hr
total speed Rahul drove for = (60 + 70)kmph = 130 kmph
⁂ average speed Rahul travelled in =
\frac{total \: speed}{total \: time}
totaltime
totalspeed
\begin{gathered}= \frac{130}{5} kmph \\ = 26 \: kmph\end{gathered}
=
5
130
kmph
=26kmph
Then, the average speed is 26 kmph.
Answer:
The average speed during whole journey is 26 kmph
