Given:
• Train travels Distanced with speed (v1) = 60m/h
. Another distance Travelled by train = 2d with speed (v2) = 80m/h
To Find :
• Average speed
Formula Used:
•Average Speed = total distance / total time
Solution :
★ Total Time (T)
➡t=s/v
t1=d/60
t2=2d/80
→ t2=d/40
→T=t1+t2
→ Td/60+ d/40
➡T=d/60 +d/40
t= 40d + 60d / 60 × 40
→T=d 24
Average Speed = total distance / total time
→ d+2d
_______
d
_______
24
3d × 24 /d
=> Vay =72m/h
Answer:
Average speed of train is 72 m/h
here's the answer hope it helps you
