Question

a man covered half distance with speed v and reamaing half with Speed v1 and v2 for equal time interval find average speed?
$2v1v2 \div v1 + v2$
peed​

Answer 1

Answer:

average speed=2v(v1+v2) /2v+v1+v2

Explanation:

for equal time the, average speed = v1+ v2 /2 ,then there is mentioned that half distance,so for equal distance ,average speed= 2v1v2/ v1+ v2

so, v1=v and v2= v1+v2/2

then the answer
