Average speed  =  (distance covered) / (time to cover the distance)

                           =  (30km + 40 km)  /  (25min + 35min)

                           =        (70 km)  /  (60 min)

                           =             70 km/hour

Answer:

70 kmph

Explanation:

Speed = [tex]\frac{Distance}{Duration}[/tex]

Distance is the total length of the path irrespective of the direction.

S = 30 km + 40 km

S = 70 km

Duration is the time taken to move from the initial point to the final point

t = 25 min + 35 min

t = 60 min

t = 1 hour

Speed = [tex]\frac{Distance}{Duration}[/tex]

[tex]v = \frac{S}{t} \\\\v = \frac{70}{1} \\\\v = 70 km/hour\\\\v = 70 kmph[/tex]
