Question

Freistance traveled by a train is 495 km in 4 hours 30 minutes, what is its speed?​

Answer 1

Answer:

• 110 km/h is the speed of train.

Step-by-step explanation:

Given:-

• Distance travelled ,d = 495 km

• Time taken ,t = 4 hours & 30 min

To Find:-

• Speed ,s

Solution:-

Conversion of Unit.

4 hours 30 min = 4 + 1/2 = 9/2 = 4.5 h

As we know that Speed is defined as the distance travelled by body in per unit time .

• S = d/t

where ,

• S denotes speed
• d denote distance
• t denote time

Substitute the value we get

→ S = 495/4.5

→ S = 4950/45

→ S = 110 Km/h

• Hence, the speed of the train is 110 km/h.

Answer 2

Answer:

Given :-

• Distance travelled by car in 4 hours and 30 min = 495 km

To Find :-

Speed of train

Solution :-

Firstly we will convert unit.

$\tt \: 4 + \dfrac{1}{2} = \dfrac{9}{2} = 4.5 \: hr$

As we know that

$\huge \tt \: S = \frac{d}{t}$

Here,

S is the speed

D is the distance

T is the time

$\tt \: S = \dfrac{495}{4.5}$

$\tt \: S = 110 \: kmph$

Hence :-

Speed of train is 110 km/h
