Question

how long a train will take to travell a distance of 200km with a speed of 60 km per hour.
​

Answer 1

Answer:

The train will take 3.3 hr to reach 200 km at a speed of 60 km/hr

Answer 2

Answer:

12 is the ans

Explanation:

speed = distance / time

$1km = 1000m \\ 1hour \: = 3600sec \: \\ \frac{60 \times 1000}{1 \times 3600} = \frac{60000}{3600} \\ = \frac{100}{6} \\ speed = \frac{distnce}{time} \\ \frac{100}{6} = \frac{200}{t} \\ 100t = 200 \times 6 \\ t = \frac{1200}{100} \\ t = 12$
