Question

A train travles 25km in 0.5hrs.How fast is the train going?

Answer 1

Answer:

50km/h

Step-by-step explanation:

if 25km/30 min, then we want to convert 30 minutes to a hour, which is times 2.

So like a ratio we also have to multiply 25 by 2, which equals 50.

So 50km/h.

Answer 2

Answer:

∴  The speed of a train in km/hr is $50$ km/hr.

Step-by-step explanation:

• In context with question asked,
• We have to find the speed of a train in km/hr.
• It is given that the distance covered by train in $0.5$ hour = $25$ km
• We know that, $0.5$ hour * $2=1$ hour
• So, to find the speed of a train in km/hr, we have to multiply the distance covered by train in $0.5$ hour by $2$.
• Hence,

         The speed of a train = $25\times 2$

                                       = $50$ km/hr

• ∴  The speed of a train in km/hr is $50$ km/hr.
