Answer 1

Answer:

50  MINUTES

Step-by-step explanation:

avg.speed = distance / time

avg.speed in first case = 25/60/60 or 25 / 1 (1 hour = 60 min)

hence avg peed  =  25 km/h

New avg.speed = 25 +5 = 30

time= distance / avg speed

hence, time = 25 / 30

time = 5/6 hr or 50 min.

It will take 50 mins.
