Bess [88]

Answer:

Georgio drives 10 miles east, then 16 miles north, then 4 miles north again. Find the distance from his starting point to his en
larisa86 [58]

Answer:

22.36 mile.

Step-by-step explanation:

Please see attached photo for explanation.

In the attached photo, y is the distance between starting point and the end point.

Thus we can obtain the value of y by using the pythagoras theory as show below:

Note: y is the longest side other wise known as the Hypothenus.

y² = 10² + 20²

y² = 100 + 400

y² = 500

Take the square root of both side

y = √500

y = 22.36 mile

Therefore, the distance between the starting point and the end point is 22.36 mile

Now we are told to get the ratio of length of car to length of model.

This means 108:6 = 18:1
