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

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

Step-by-step explanation:

area of the trapezoid = area of the 2 triangles +

area of the rectangle

i) area of triangle on left:

a = ½ bh

a = ½ × 2 × 9

a = 9 in²

ii) area of triangle on right:

a = ½ bh

a = ½ × 2 × 9

a = 9 in²

iii) area of rectangle = length × width

a = l × w

a = 12 × 9

a = 108 in²

iv) area of trapezoid = 9 + 9 + 108

= 126 in²

hope this helps you!
