Answer 1

Answer:

none of these

Step-by-step explanation:

average speed is total distance by time taken

that is 10+20÷5=6

so none of the above

this is y guess I don't know whether it is crct r not

Answer 2

Answer:

None of these

Step-by-step explanation:

We have given that person first travels 10 km in 2 hrs and after taking rest of 1 hr he starts to travel again and then he travels for 20 km in 3 hrs

Therefore total distance he travels=50 km

Total time is taken by him to travel 30 km=5 hrs

So we know that $S=\dfrac{D}{T}$

$S=\dfrac{30}{5}$=6
