Two trains left the station at the same time, but took different tracks to their destination. One took a track that was 200 miles long and it went 50 MPH. The other took the other track that was 240 miles long and it went 80 MPH. How much time did it take them on average? (Round to the nearest integer.)
Ду қатора дар як вақт истгоҳро тарк карданд, аммо ба самтҳои гуногун рафтанд. Яке роҳи 200 милро гирифт ва бо суръати 50 мил дар соат ҳаракат кард. Дигар роҳе, ки 240 мил буд, гирифт ва бо суръати 80 мил дар соат ҳаракат кард. Онҳо дар миёна чӣ қадар вақт гирифтанд? (Ба наздиктарин адад гардонед.)
How many hours did the first train take? ** The first train took 5 hours because 200 / 40 = <<200/40=5>>5
How many hours did the second train take? ** The second train took 3 hours because because 240 / 80 = <<240/80=3>>3
How many hours did the first and second trains take? ** The total time was 8 hours because 5 + 3 = <<5+3=8>>8
How many hours did the first and second trains take on average? ** The average time was 4 hours because 8 / 2 = <<8/2=4>>4
#### 4
Чанд соат аввалин қатора гирифт? ** Аввалин қатора 5 соат гирифт, зеро 200 / 40 = <<200/40=5>>5  
Чанд соат дуюмин қатора гирифт? ** Дуюмин қатора 3 соат гирифт, зеро 240 / 80 = <<240/80=3>>3  
Чанд соат аввалин ва дуюмин қатораҳо гирифтанд? ** Вақти умумӣ 8 соат буд, зеро 5 + 3 = <<5+3=8>>8  
Чанд соат аввалин ва дуюмин қатораҳо дар миёна гирифтанд? ** Вақти миёна 4 соат буд, зеро 8 / 2 = <<8/2=4>>4
