Answer 2

Answer:

Train moving with speed of 80 km/hrs will cover 120 km in 1 hour 30 minutes.

Step-by-step explanation:

• Speed of an object is defined as the rate of change of distance with time.
• In other words, we can say that it is the distance travelled by an object in unit time.
• Mathematically, speed is defined as:

$speed = \frac{distnce}{time}$

• S.I. unit of speed is meters/ sec.

• In the question it is given that :
• speed of train = 80 km/hrs
• distance travelled by train = 120 km
• Hence, time taken by train to complete this distance is :

$time \: taken = \frac{distance \: travelled}{speed \: of \: train} \\ = \frac{120}{80} \: hrs. \\ = 1.5 \: hrs.$

• To convert hours into minutes, we multiply by 60.

$0.5 \: hrs \times 60 = 30 \: minutes$

• Hence, total time taken by train to cover 120 km with a speed of 80 km/hrs. is 1 hour and 30 minutes.
• Train will reach its new destination at 12:20 pm.
