Question

a train a uniform speed covers a distance of 255 km in 1.30 hours find the speed of train and distance covered in 3.45 hours

Answer 1

Answer:

The speed and distance is 170 km/hr and 646 km.

Step-by-step explanation:

Given that a train at a uniform speed cover a distance of 255 km in 3/2 hours.

We have to find the speed of the train and the distance covered in 19/5 hours

As

Speed = Distance / Time,

Speed = 255 / (3/2) = 170 km/h.

As train at uniform speed remains constant

i.e. Speed=170 km/hr

Now, we find the distance covered in 19/5 hours.

Speed = Distance / Time,

170 = Distance / (19/5)

Distance = 170 * ( 19/5) = 646 km

Answer 2

Answer:

648 km

Step-by-step explanation:

$s = \frac{d}{t} \\ s = \frac{255km }{1.5h} \\ \frac{2550}{15} = \frac{170}{1} \\ s = 170km \: per \: h \\ \\ d = s \times t \\ d = 170 \times 3.8 \\ = 17 \times 38 = 648 \: km$
