Explanation:

$\sf We\:know\:that\:v_{avg}\\ \\ \sf\frac{total \: distance}{total \: time} \\ \\ \sf \: v_{avg } \: = \frac{100}{2} = 50 \: km/hr \\ \\ \sf \: so \: average \: speed \: is \: 50km/hr$

Answer 2

Here we are given distance and time

We have to find the average speed

Now, in order to find the average speed, we will use the formula

$average speed =\frac{total distance}{total time}$

Total distance = 100 km + 50 km

                       = 150 km

Total time = 2 hours + 1 hour

                = 3 hour

Putting the values in the formula

$Average speed = \frac{150}{3}$

                       = 50 km/hr

So, the average speed will be 50 km/hr
