correct answer is (b) which is 30 minutes

Answer 2

Answer:

Step-by-step explanation:

Here,

distance=x

speed=6km per h

time= 50 mins

Now,

speed= distance upon time

6=x/50

x= 6*50

 =300km

Again,

disatnce=x=300 km

speed=10km per h

So,

speed= distance upon time

10=300/time

time=30 mins

ANSWER=30 mins
