Question

If while going to your school , your speed was 40 km/h and while returning through the same path your speed was 30 km/h ,then what was your average speed of the whole journey?​

Answer 1

Answer:

V1 = 40 and V2 = 30

So average speed =2× v1 × v2 / ( v1+ v2)

2 ×30× 40/(30+40) = 240/70 = 30.428 km/h

Explanation:

Answer 2

Answer:

Average speed =35km/hr

Explanation:

V1=40km/hr

V2=30km/hr

Average speed =(V1+V2) /2

=(40+30) /2

=70/2

=35km/hr
