Question

A train cover distance of of 70 3/4in 1 hour .how much distance will be cover in 3 3/4hours

Answer 1

The train will cover a distance of 265.5 km in 3\dfrac{3}{4}\ hours.

Step-by-step explanation:

In this case, it is given that, A train covers a distance of 70\dfrac{4}{5}\ km in 1 hour. We need to find the distance will it cover in 3\dfrac{3}{4}\ hours.

We know that,

70\dfrac{4}{5}\ km=\dfrac{354}{5}\ km

and

3\dfrac{3}{4}\ hours=\dfrac{15}{4}\ hours

It can be done using unitary method. The distance covered by train in 3\dfrac{3}{4}\ hours  is :

d=\dfrac{354}{5}\times \dfrac{15}{4}\\\\d=265.5\ km

So, the train will cover a distance of 265.5 km in 3\dfrac{3}{4}\ hours. Hence, this is the required solution.
