Detailed Solution

Concept: the formula speed =

\frac{distance}{time}

can be changed.
Distance equals speed times distance times time, and time equals distance times speed.……………………. (3)
We require the other two in order to calculate one of the variables (speed, distance, or time) .
Km to m conversion

1 kilometer = 1000 m

(4) Converting an hour to minutes

1 hr = 60 \min \dots \dots \dots \dots \dots \dots \dots . (5)

The train's speed is

92.4 km / h .

Using

equations (4) and, let' s calculate in m / \min (5)

Speed:

\frac{92.4 \times 1000}{60} = \frac{92400}{60} = 1540 meters per second .

Time: 10 minutes
Equation (2) reads

Distance = 1540 \times 10 = 15400 m .

Hence, the correct option is 1) 15400
