A car travels 21 km in 16 minutes. What is its average speed in km/h?

bekas [8.4K]

Answer:

78.6km/h

Step-by-step explanation:

Speed=distance÷time

distance=21km

time=16 minutes(convert into hour by dividing it with 60)

=16÷60=0.267

Speed=21÷0.267=78.65km/h

$speed = \frac{distance }{time}$

$speed = \frac{21}{0.267} = 78.6km(h$

Which is better: Car A that travels 308 miles on 11 gallons of gasoline OR Car B that travels 406 miles on 14 gallons of gasolin

Jet001 [13]

$\begin{gathered} \text{Car A travels 308 miles on 11 gallons, so, the ratio of miles per galon is} \\ \frac{308}{11}=28\text{ miles per gallon} \\ \\ \text{for the car B, the ratio is} \\ \frac{406}{14}=29\text{ miles per gallon} \end{gathered}$

thus, the best car is car B,because it can tavel 29 miles with only one gallon,andcar A can only travel 28 miles with one gallon.

What is the area of the largest rectangle with lower base on the x-axis and upper vertices on the curve y = 12 - x2? (4 points)

wolverine [178]

Answer: 16 square units

Step-by-step explanation:

let the vertex in quadrant I be (x,y)

then the vertex in quadratnt II is (-x,y)

base of the rectangle = 2x

height of the rectangle = y

Area = xy

= x(12 - x²)

= -x³ + 12x

d(area)/dx = 3x² - 12 = 0 for a maximum of area

3x² = 12

x² = 4

x = ±2

y = 12-4 = 8

So, the largest area = 2 x 8 = 16 square units
