11. A bus covers a distance of 30km in one hour. In the next one hourit covers the distance of 50km. average speed of the bus is

1) 40m/s

2) 40km/hr

3) 39km/hr

4) 42km/hr

$\huge\fcolorbox{red}{yellw}{Solution}$

$\boxed{Average \: Speed \: = \frac{Total \: distance}{Total \: time \: } }$

➣ Average Speed =

= 30 km + 50 km

1 hour + 1 hour

➣ Average Speed = 80/2

➣ Average Speed = 40kmph

$\boxed{Average \: Speed \: = 40kmph}$
