# What are these math problems called and how do you figure them out?

I’ve been out of high school for about 6 years now so I don’t remember anything about this. But what type of math is it where you have to calculate when an object will reach a destination using it’s speed and distance away? And how do you figure it out? Maybe it’s a ‘brain fart’ and really easy, but I can’t figure it out….Your GPS does it.

Give me an actual problem, please!

@Val123 I don’t have an actual example. I meant the problems where they are stated: Hurricane so and so is heading for weather station X at 15MPH, it’s 1500Z, so when will the hurricane reach your station if it is 300 miles away. Or something like that lol.

Those problems for me are always called the: Yeah, I’m Gonna Take a Pass On That, Chuck

Way above my math skills.

It’s simple algebra until you start adding in vectors, which may involve trigonometry or calculus.

Distance/Speed = ETA

so… 300 miles / 15 mph = 20 hours

just make sure your distance and speed are using the same measurements (miles : miles, or meters : meters, none of this inches : meters business)

@wonderingwhy Ah I see, I thought it was something along those lines, thank you :)

There are two kinds of problems that ask when an object reaches its destination. (1) Constant velocity; and (2) constant acceleration.

The 1st kind uses a linear formula—distance proportional to time.

The 2nd kind uses a quadratic formula—distance proportional to time-squared.

There are other possibilities than these 2, but you’ll probably do these 2 kinds first.

Time and Distance problems?
