Answer 2

The length of 2/5th of the road is 60 kilometres.

Given - 3/10th of a road is 45km

Find - length of 2/5th of the road is

Solution - Let the total length of road be x. Now, using the first part of equation to find the total length of road. Then calculating the required distance of the road.

Representing first part of question as mathematical equation -

$\frac{3}{10} \times x = 45$

Shifting the denominator on Left Hand Side at numerator on Right Hand Side

$3 \times x = 45 \times 10$

Performing multiplication on Right Hand Side

$3 \times x = 450$

Shifting the value on Left Hand Side at denominator in Right Hand Side

$x = \frac{450}{3}$

Performing Division to find the value of x

x = 150 km

Now, the length of 2/5th of the road

Length = $\frac{2}{5} \times x$

Length = $\frac{2}{5} \times 150$

Performing multiplication and division

Length = $2 \times 30$

Length = 60 km

Hence, the length of 2/5th of the road is 60 kilometres.
