James lives 3.42 kilometers from school. Megan lives 0.76 kilometers from school. The distance James lives from school is how ma

Eddi Din [679]

Answer:

The distance of James from school is 4.5 times longer than the distance of Megan from school.

Step-by-step explanation:

Given:

Distance of James from school = 3.42 km

Distance of Megan from school = 0.76 km

Now, in order to find how many times James distance from school is longer than that of Megan, we have to divide the larger distance by the smaller distance.

Here, James lives at a larger distance of 3.42 km.

So, the ratio of the two distances is given as:

$\frac{\textrm{Distance of James from school}}{\textrm{Distance of Megan from school}}=\frac{3.42\ km}{0.76\ km}\\\\\frac{\textrm{Distance of James from school}}{\textrm{Distance of Megan from school}}=4.5\\\\\textrm{Distance of James from school}=4.5\times (\textrm{Distance of Megan from school})$

Therefore, the distance of James from school is 4.5 times longer than the distance of Megan from school.
