A car travels for 2 hours 15 minutes at an average speed of 64 mph. Calculate the distance travelled.

231.746 km

Step-by-step explanation:

In order to find the answer to this question we will have to answer it using what the question gives us.

The car traveled for 2 hours and 15 minutes

The average speed of the car was 64 mph (miles per hour)

2 hours = 64 + 64 = 128

15 minutes is 1/4 of a hour which means you need to divide miles per hour by 4

64 ÷ 4 = 16 or 16+16+16+16 = 64

128 + 16 = 144 distance total

Since the answer needs to be in kilometers we need to convert miles into kilometers.

We know that..

1 mile = 1.60934 km

Which means you need to multiply 1.60934 by 144 (total number of miles) to find your answer in kilometers.

1.60934 × 144 =231.746km

= 231.746km

Hope this helps.

answer: plz give a pic and answer choices so i can answer!

step-by-step explanation:

g(x) = 3*(8(3^(x−2))+2)

g(x) = 24 (3^(x-2) )+6

the factor is 2

step-by-step explanation:

let f(x)=8(3^(x−2)+2)

to stretch a graph by 3, it would be 3f(x)

g(x) =3f(x)

g(x) = 3*(8(3^(x−2))+2)

g(x) = 24 (3^(x-2) )+6

x     −2     0     2     4     6

f(x) 1/64 1/16   1/4     1     4

1/64 * z * z = 1/16

i multiplies by z twice because it its 2 steps from -2 to 0

1/64 z^2 = 1/16

multiply by 64 to clear the fraction on the left side

1/4 * 64 z^2 =1/16 *64

z^2 = 4

take the square root of each side

sqrt(z^2) = ±sqrt(4)

z = ±2  

we are multiplying by 2 each time.
