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
For shapes to be similar, their ratios of length-to-length and width-to-width must be the same. When you divide the larger length by the smaller length and the larger width by the smaller width, do you get the same number? No, so these rectangles are not similar.
