An air force plane left singapore and flew toward the maintenance facility at an average speed of 150 mph. a cargo plane left some time later and flew in the same direction but an average speed of 180 mph after flying for 5 hours the cargo plane caught up with the air force plane. how long did the air force plane fly before the cargo plane caught up?

The Air force plane fly 150 miles before the cargo plane caught up.

Step-by-step explanation:

Since we have given that

Average speed of Air force = 150 mph

Average speed of Cargo = 180 mph

They both flew in the same direction, So,

Relative speed = 180-150 =30 mph

Number of hours = 5 hours

So, Distance would be

Hence, the Air force plane fly 150 miles before the cargo plane caught up.
