Respuesta :
Average speed = (distance covered) / (time to cover the distance)
= (30km + 40 km) / (25min + 35min)
= (70 km) / (60 min)
= 70 km/hour
= (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]
