Answer 1

$\huge{\underline{\underline{\purple{\sf{Question}}}}}$

1) An object moves 100m distance in 5 seconds , find it's speed ?

2) Find the distance covered by a car in 10 sec , if it is moving at the speed of 20m/s .

$\huge{\underline{\underline{\purple{\sf{Solution}}}}}$

1)

$\sf{Given:-}$

$\sf{Distance=100m}$

$\sf{Time=5s}$

We know that,

$\huge{\green{\boxed{\boxed{\sf{Speed= \frac{Distance}{Time}}}}}}$

Using the formula we get:-

$\longrightarrow$$\sf{Speed=\frac{500m}{5s}}$

$\longrightarrow$$\sf{Speed=100m/s}$

The speed with which the object moves is 100m/s.

2)

$\sf{Given:-}$

$\sf{Speed=20m/s}$

$\sf{Time=10s}$

We know that,

$\huge{\green{\boxed{\boxed{\sf{Distance=Speed×Time}}}}}$

Using the formula we get:-

$\longrightarrow$$\sf{Distance=(20×10)m}$

$\longrightarrow$$\sf{Distance=200m}$

The car covered 200m in 10sec with the moving speed 20m/sec.

Answer 2

Answer:

(a) the speed of the object is 20 m/s.

(b) The distance covered by the car is 200 m.

Explanation:

(a) Given Data :

Distance travelled = 100 m

Time taken = 5 seconds

To be Calculated :

Speed of the object

Formula To be Used :

$speed \: = \frac{distance \: covered}{time \: taken}$

Calculations :

$speed \: = \frac{distance \: covered}{time \: taken} = \frac{100}{5} = 20m {s}^{ - 1}$

Hence, the speed of the object is 20 m/s.

(b) Given Data :

Speed of the car = 20 m/s

Time taken = 10 sec

To Be Calculated :

Distance Covered by the car

Formula To Be Used :

$distance \: = speed \: \times time$

Calculations :

$distance \: = speed \: \times time \\ distance \: = 20 \: m {s}^{ - 1} \times 10 \: s \: = 200 \: m$

Hence, The distance covered by the car is 200 m.
