Question

at a speed of 56 km per hour a train take 4 hour for a journey Find how long it would take at64 km per hour​

Answer 1

Answer:

16

Step-by-step explanation:

56/ 4 = 14

then 64 / 4 =16

Answer 2

Required Answer :

The train will take 3.5 hours to cover a distance at a speed of 64 km/h

Given :

• Speed of a train = 56 km
• Time = 4 hours

To find :

• How much time the train will take to travel a distance speed of 64 km per hour

Solution :

Using formula,

• D = S × T

where,

• D denotes the distance travelled by the object
• S denotes the speed of the object
• T denotes the time taken by the object

Substituting the given values :

⇒ Distance = 56 × 4

⇒ Distance = 224

Distance travelled by the train = 224 km

Now, let's find the time :

we have,

• Speed of the train = 64 km/h
• Distance = 224 km

Using formula,

• Time = Distance ÷ Speed

Substituting the given values :

⇒ Time = 224/64

⇒ Time = 112/32

⇒ Time = 56/16

⇒ Time = 28/8

⇒ Time = 14/4

⇒ Time = 7/2

⇒ Time = 3.5

Therefore,

• The train will take 3.5 hours to cover a distance at a speed of 64 km/h
