Hey mate✔✔your answer is⏩here......
=====>Distances:<=====
==> D1 = 2500 KM
==> D2 = 1200 KM
==> D3 = 500 KM
=====>Speeds:<=====
==> S1 = 500 KM / H
==> S2 = 400 KM / H
==> S3 = 250 KM / H
{{{{{{Then Total time:}}}}}}
==> Time = Distance/Speed <==
==> T1 = 2500/500 = 5 H
==> T2 = 1200/400 = 3 H
==> T3 = 500/250 = 2 H
Now,
=> Total Distance :
==> D = D1 + D1 + D3
==> D = 2500 + 1200 + 500
==> D = 4200 KM
=> Total Time :
==> T = T1 + T2 + T3
==> T = 5 + 3+ 2
==> T= 10 H
At last : )
=> Average Speed = Total Distance / Total time
==> Averag speed = 4200 / 10
⏩⏩✔✔ Average Spees = 420 KM / H✔✔
Hope it helps you........
