It takes a train the same time to travel 320 miles as it takes a bus to travel 200 miles. If the train is traveling 30 mph faster than the bus, find the rate at which the bus is traveling Write an equation that will help solve this problem use x as the variable

What is the speed of the bus?

In other words, the distance you drove is equal to the rate at which you drove times the amount of time you drove. For an example of how this would work in real life, just imagine your last trip was like this:

You drove 25 miles—that's the distance.

You drove an average of 50 mph—that's the rate.

The drive took you 30 minutes, or 0.5 hours—that's the time.

According to the formula, if we multiply the rate and time, the product should be our distance.

And it is! We drove 50 mph for 0.5 hours—and 50 ⋅ 0.5 equals 25, which is our distance.

What if we drove 60 mph instead of 50? How far could we drive in 30 minutes? We could use the same formula to figure this out.

60 ⋅ 0.5 is 30, so our distance would be 30 miles.

a variable is any characteristics, number, or quantity that can be measured or counted. a variable may also be called a data item. hope i !
