Question

A train travelling at a uniform speed covers a distance of 255 km in 1½ hours. Find the speed of the train and the distance covered in 3⅘ hours. ​

Answer 1

Answer:

Given:-

Distance=255km

T=1.5 hr

Formula used:-

$S= \frac{D}{T}$

Solution 1:-

$S= \frac{255km}{1.5h}$

S= 170km/h

Solution 2:-

Speed=170km/h

Hence,

Speed in

$3 \frac{4}{5} hr$

$= \frac{19}{5}$

Distance=S×T

$\frac{19}{5} \times 170$

=646km
