Answer:

Speed = \frac{38}{3}km/hr

Step-by-step explanation:

Given

Distance = 3\frac{1}{6}km

Time = \frac{1}{4}hr

Required

Determine the average speed

Average speed is calculated as thus;

Speed = \frac{Distance}{Time}

Speed = 3\frac{1}{6}/\frac{1}{4}

Speed = 3\frac{1}{6} * \frac{4}{1}

Convert Mixed Fraction to Improper fraction

Speed = \frac{19}{6} * \frac{4}{1}

Speed = \frac{19 * 4}{6 * 1}

Speed = \frac{76}{6}

Divide both sides of the fraction by 2

Speed = \frac{38}{3}

Hence:

The speed is:

Speed = \frac{38}{3}km/hr

son4ous [18]

Answer:

$18

Step-by-step explanation:

Given:

6.4x - 2.1x = 77.4

Where,

x = cost of sheet metal per square foot

How much does sheet metal cost per square foot?

6.4x - 2.1x = 77.4

4.3x = 77.4

Divide both sides by 4.3

x = 77.4 / 4.3

= 18

x = $18

Sheet metal per square foot cost $18

amid [387]

Answer:

Sadie took 47 minutes to finish her test.

Step-by-step explanation:

Let Laura's time be x minutes.

Then we have:

x + 3x - 16 = 68

4x = 84

x = 21 minutes.

So Sadie took 3(21) - 16 = 63-16

= 47 minutes.
