A children's roller coaster ride travels along 3,300 feet of track at an average rate of 15

Olenka [21]

Answer:

150 seconds

Step-by-step explanation:

Remember that

$1\ mile=5,280\ feet$

To convert miles to feet multiply by 5,280

$1\ hour=3,600\ seconds$

To convert hours to seconds, multiply by 3,600

step 1

Convert the average rate of miles per hour to feet per second

$15\frac{mi}{h}=15(\frac{5,280}{3,600})=22\frac{ft}{sec}$

step 2

Find out how many seconds does the ride take to travel this length of track

we know that

The length of the track is 3,300 ft

Divide the total length of the track by the speed

$\frac{3,300}{22}= 150\ sec$

Can someone please answer. There is a picture. It is only one question. Thank you so much!

We can check each of these using the Pythagorean Theorem, $a^2 + b^2 = c^2$
Option A:
$.5^2 + 1.2^2 = 1.3^2

$
.25 + 1.44 = 1.691.69 = 1.69
This option works
Option B
$1^2 + 2^2 = 3^2$
1 + 4 = 9
5 ≠ 9
This option does not work, but let's check the others to make sure
Option C:
$6^2 + 8^2 = 10^2$
36 + 64 = 100
100 = 100
This option works
Option D:
$3^2 + 4^2 = 5^2$
9 + 16 = 25
25 = 25
This option works

So, after doing the calculations, we see that option B does not work
