12.

A red car travels 400 m in 20s. A blue car travels 660m in 30s. Which car has the greater average speed

Answer»

ANSWER:

BLUE CAR IS FASTER THAN RED CAR.

GIVEN:

For red car

Distance traveled = 400m
Time taken = 20 sec

For blue car

Distance traveled = 660m
Time taken = 30 sec

TO FIND:

Which car has greater speed?

ANSWER:

Formula

$\implies \: average \: speed \: = \frac{total \: distance}{total \: time} \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \\ for \: red \: car \\ \: \implies \: average \: speed \: = \frac{400}{20} \\ \implies \: average \: speed \: = 20ms {}^{ - 1} \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \\ for \: blue \: car \\ \implies \: average \: speed \: \: = \frac{total \: distance}{total \: time} \\ \implies \: average \: speed \: \: = \frac{660}{30} \\ \implies \: average \: speed \: = 22ms {}^{ - 1}$

BLUE CAR IS FASTER THAN RED CAR

NOTE:

some IMPORTANT FORMULAS

$\implies \: average \: velocity = \frac{total \: displacement}{total \: time} \\ \implies \: average \: speed = \frac{total \: distance}{total \: time}$

In the examination a candidate must get 3/8th marks to pass, out of total marks.Shyam appeared in the exam and got 300 marks and still failed by 36 marks. Themaximum mark is:

Answer»

Answer:

The MAXIMUM marks is 896.

Step-by-step EXPLANATION:

Let the total or maximum marks be X

Passing marks = 3/8 of x = 3/8 × x = 3x/8

Marks Shyam got = 300

Failed by marks = 36

Therefore, 3x/8 - 300 = 36

Or, 3x - 2400/8 = 36

Or, 3x - 2400 = 36 × 8 = 288

Or, 3x = 2688

Step-by-step explanation:

Given *This puzzle will kill your mind* 9999=4 8888=8 1816=3 1212=0 1919=?

Given 9999 = 4
8888 = 8
1816 = 3
1212 = 0
1919 = ?
Now this is a puzzle where in we need to find what is 1919
Now there are SMALL circles in a number, for EXAMPLE there is a circle in the number 9.So we need to find the number of circles in the given numbers
So 9999 has 4 circles SIMILARLY
8888 has 8 circles
1816 has 3 circles
1212 has 0 circles

THEREFORE 1919 has 2 circles.(drawing of circles in numbers)
