<PRE><B>Question 737685</B>
If a train travels 270 miles in 3 hrs. How far will it travel in 4.5 hrs ?


First I will assume 4.5 hours to mean 4 hours and 30 minutes.

270 / 3 = 90 mph

The train is cruising at 90 mph

So in 1 minute the train will travel:

90 / 60 = 1.5 miles

In 1 minute the trail will travel 1.5 miles.

Therefore:

In 4 hours the train will travel:

90 * 4 = 360 miles

In 30 minutes the train will travel:

30 * 1.5 = 45 miles

Therefore:

360 + 45 = 405 miles



Answer:

405 miles
