a motor bike travels 240 km in 4 hours. How long will it take to travel 450 km
Answer:
7 hours and 30 minutes
Step-by-step explanation:
[tex]240 \div 4 = 60km \: per \: h[/tex]
[tex]450 \div 60 = 7.5 = 7h \: 30min[/tex]
It will take motor bike 7.5 hours to cover 450 Km of distance.
What is Speed in Kinematics?Speed of a body is defined as the distance travelled by it per unit time taken to cover the distance.
Mathematically-
S = Δd/Δt or S = {d(2) - d(1)}/{t(2) - t(1)}
It is a scalar quantity as it only has magnitude and no direction.
Given is a motor bike travels 240 km ins 4 hours.
We can calculate the speed of the bike as -
s = 240/4 = 60 Km/hr
Then, the time taken to cover 450 Km will be -
t = 450/60
t = 7.5 hours
Therefore, it will take motor bike 7.5 hours to cover 450 Km of distance.

Here is a rectangle ABCD.
A
B
20 cm
D
30 cm
The length of the rectangle is increased by 10%.
The width of the rectangle is increased by 5%.
Find the percentage increase in the perimeter of the rectangle.
answer
15.5%
Step-by-step explanation:
length = 30
30+10%=33
breadth=20
20+5%=21
area of rectangle = length × breadth
600² centimeters = 30 × 20
693² centimeters = 33 × 21
Increase = 15.5%

Answer:
See under for the sequence
Step-by-step explanation:
The term with -X⁴ comes first because 4 is the highest power of x.
Then comes 7x³y³ because 3 is the second highest power

1 3/4 x 1 1/3 give your answer as a mixed number
Answer:
2 1/3
Step-by-step explanation:
1 3/4 is equivalent to 7/4
1 1/3 is equivalent to 4/3
7/ 4 x 4/3
reduce with greatest common factor so the two 4 are out (show a line crossing out the top and bottom 4 )
now you're left with 7 x 1/3 = 7/3
7/3 = 2 1/3
The product of two given mixed fractions is [tex]2\frac{1}{3}[/tex].
The given mixed fractions are [tex]1\frac{3}{4}[/tex] and [tex]1\frac{1}{3}[/tex].
What is the product of two fractions?The product of two fractions is the product of the numerators and the product of the denominators.
Product of two fractions = Product of their denominators / Product of their numerators.
Here, the mixed fraction [tex]1\frac{3}{4}[/tex] can be written as [tex]\frac{7}{4}[/tex] and the mixed fraction [tex]1\frac{1}{3}[/tex] can be written as [tex]\frac{4}{3}[/tex].
Now, 7/4 × 4/3
= 7/3
= [tex]2\frac{1}{3}[/tex]
Therefore, the product of two given mixed fractions is [tex]2\frac{1}{3}[/tex].
