Question

a train travels 80 km in one hour how far will it travel in 15 minutes

Answer 1

speed = 80km/hr
distance = 80 × 15/60 =20 km

Answer 2

Answer:

Distance travelled in 15 minutes be 20 km .

Step-by-step explanation:

As given

A train travels 80 km in one hour .

i.e

80 km = 1 hour

As 1 hour = 60 minute

Thus

80 km = 60 minute

$Distance\ travelled\ in\ 1\ minute = \frac{80}{60}$

Now

$Distance\ travelled\ in\ 15\ minute = \frac{80\times 15}{60}$

$Distance\ travelled\ in\ 15\ minute = \frac{1200}{60}$

                                                               = 20 km

Therefore the distance travelled in 15 minutes be 20 km .
