0.2% becouse
0.002=2/1000=0.2/100
The truck can cover 145 miles in 2.5 hours, so the speed of the truck is
145÷2.5=58 miles per hour
the car's speed is 1.5 times faster: 58×1.5=87 miles per hour
suppose in x hours they will meet:
distance covered by truck in x hour: 58x
distance covered by car in x hour: 87x
total distance: 145 miles
58x+87x=145
x=1
The surface area of the smaller solid is 112 km².
<h3>What are Similar Solids?</h3>
Similar shapes are enlargements of two shapes using a scale factor.
The ratio of the volume of similar solids is the ratio of the cube of their length.
Formula:
- V/v = L³/l³................... Equation 1
- L/l = ∛(V/v)............... Equation 2
Where:
- V = Volume of the larger solid
- v = volume of the smaller solid
- L = Length of the larger solid
- l = Length of the smaller solid.
From the question,
Given:
Substitute the value into equation 2
To calculate the area of the smaller solid, we use the formula below
Where:
- a = Area of the smaller solid.
- A = Area of the larger solid
make a the subject of the equation
- a = (l²A)/L²................ Equation 2
From the question,
Given:
Substitute these values into equation 2
- a = (4²/9²)567
- a = 112 km²
Hence, the surface area of the smaller solid is 112 km².
