A car travels 240 miles in 4 hours. at this rate, how many miles will it travel in 8 hours

First you need to find the rate. This problem is based on the formula d = rt

d = distance

r = rate

t = time.

The question is asking how many miles will it travel in 8 hours so to find this out we need to find the rate when the car travels 240 miles in 4 hours. We use this information and plug it into the model d = rt

d = 240

r = don't know yet

t = 4 hr

d = rt

240 = 4r

240 / 4 = 4r / 4

60 = r

r = 60

So the car is going at a rate of 60 miles per hour. Now that we know this we can solve for how many miles the car will travel in 8 hours.

d = rt

d = r * t

d = 60 * 8

d = 480

So the car will travel 480 miles in 8 hours

Another way to think about this is that you know the car traveled 240 miles in 4 hours and the question is wanting to know how far the car will travel in 8 hours, which would be double the 4 hours so 240 + 240 = 480
