Dylan and Spencer went looking for Dylan's lost dog. Dylan travelled 100 meters to the neighbour's house, 1.5 kilometres to the pet store, and 310 meters to the park, where he found the dog. Spencer travelled 1269 meters to the other side of town. How much further did Dylan travel compared to Spencer?

641 m.

Step-by-step explanation:

1 m = .001 km.

1 km = 1000 m.

Combine the already existing m measurements.

100+310 = 410.

Next, convert 1.5km to m.

1.5km = 1,500 m.

Add them both.

1,500 + 410 = 1910.

Finally, subtract and solve.

1910-1269= 641 m.

answer: the answer is 127 degrees

in problems involving proportions, we can use cross products to test whether two ratios are equal and form a proportion. to find the cross products of a proportion, we multiply the outer terms, called the extremes, and the middle terms, called the means.
