Question

train covers 35 km in 50 minutes . Find the speed in ____ km/hr 9 ​

Answer 1

Answer:

36 km/hr

Step-by-step explanation:

$Speed \: = \frac{Distance}{Time} = \frac{30\: km}{50 \: mins} =\frac{30 \: km}{\frac{50}{60}hr } = \frac{30 \times 60 \:km}{50\: hr} = 36 \: km/hr$

Answer 2

Answer:

Since,

$Speed \: = \frac{Distance}{Time}$

So, Speed =

$\frac{35 \: km}{50 \: min} = \frac{35 \times 1000 \: m}{50\times 60 \: sec}$

$= \frac{35000}{3000} \frac{m}{s}$

= 11.66 m/s

= 12m/s
