Question

a train moves at aconstant speed of 90km/hr. how for will it travel in 40minutes​

Answer 1

$s = 90 \\ t = 40min \\ \: \: \: = \frac{40}{60} \\ \: \: \: = \frac{2}{3} hrs \\ distance = s \times t \\ d = 90 \times \frac{2}{3} \\ d = 30 \times 2 \\ d = 60km$

Answer 2

Answer:

The distance traveled in 40 min. = 60 km.

Step-by-step explanation:

Speed = 90 km/h

So, Distance traveled in 1 hrs or 60 min = 90 km

∴ Distance traveled in 1 min = $\dfrac{90}{60} = \dfrac{3}{2}$ km

Distance traveled in 40 min = $\dfrac {3}{2} \times {40}$ = 60 km

Hence, the distance traveled = 60 km.
