$75 \text{ km}$
87 km
90 km
$150 \text{ km}$

Solution:

Concept:

Distance covered is given by:

\text{Distance} = \text{Speed} \times \text{Time}

Explanation:

Total time from 10.45 am to 12.15 pm is:

10.45 am to 11.45 am

= 1

hour

11.45 am to 12.15 pm

= 30

minutes

So, total time

= 1

hour

30

minutes

Convert to hours:

30

minutes

= \frac{30}{60} = 0.5

hour

Hence, total time

= 1 + 0.5 = 1.5

hours

Now,

\text{Distance} = 60 \times 1.5

\text{Distance} = 90

km

Answer:

The train will cover

90

km.
