Afreight train leaves a station traveling 60 miles per hour. thirty minutes later a passenger train leaves the station in the same direction on a parallel track at the speed of 72 miles per hour. how long will it take the passenger train to catch the freight train?

The passenger train will take 2.5 hours to catch the freight train.

Explanation

Suppose, it will take hours for the passenger train to catch the freight train.

As the passenger train leaves the station after 30 minutes or hour , so the freight train will travel the same distance as the passenger train in hours.

Speed of the freight train is 60 mph and speed of the passenger train is 72 mph.

As   , so the equation will be......

So, the passenger train will take 2.5 hours to catch the freight train.

answer: she must produce at least 9,000 windows in order to make a profit of $48,000

explanation:

48,000 - 12,000 = 36,000

36,000/4 = 9,000

step-by-step explanation:

hello and welcome!

so, when we see the words "proportional" along with a table, we need to know that we're looking numbers that divide by the same thing.

looking at this table, we simply have to do a trial and error, and divide to see which numbers have the same quotient. if you look at choice a & c, they both have equal quotients for three of the numbers, with one exception, so those can't be the answer. looking at b, there is no similarity, so that can't be it. then, we see d; if you divide all the numbers in the table, you'll see that they all divide by two, which is a proportional relationship, and our answer!

also, always remember that the x will always be the number that goes into y, and somewhere behind this table, is a formula. for this specific table, the formula would be:

since our x-value is being divided by two to get the y-value. and if they were to ask for more numbers in the series, this is the formula you would use to find them.
