Question

If the distance covered by a train is 520 km in 3 hours 20 minutes, what is its speed?

Answer 1

Answer:

157.57 km/h approx will be the answer of this question

Answer 2

Answer:

156km/h or 43.33m/s

Step-by-step explanation:

$distance = 520km = 520000m\\ time \: taken = 3h20min \: = \frac{10}{3} h \\ = 12000s \\ speed = \frac{520}{ \frac{10}{3} } = 52 \times 3 = 156km {h}^{ - 1} \\ = \frac{520000}{12000} = 43.33m {s}^{ - 1}$
