A train travels 300km in 6 hours. How long will it take to complete a journey of 550km?

Answer 1

Solution :

speed of train :

• $\dfrac{distance \: \: covered}{time}$

• $\dfrac{300}{6}$

• $50 \: km \: h {}^{ - 1}$

time taken to complete the journey of 550 km :

• $\dfrac{distance \: \: to \: \: be \: \: covered}{speed}$

• $\dfrac{550}{50}$

• $11 \: hr$

for completing journey of 550 km, it took 11 hours

Answer 2

Answer:

11 hours

Step-by-step explanation:

We know that speed= distance/time

the train traveled for 300 km(distance) in 6 hours (time) from those information we can calculate the speed

speed = distance/ time

speed = 300km/6hours = 50 km/hr

we have the speed now we will consider the train move in a constant speed

they want the time for distance of 550 km

we use the same law

speed = distance/time

time= distance/speed

time = 550/50 = 11 hours the time to complete 550 km
