Question

Lily drove from Town X to Town Y at an average speed of 78km/hr. After
$1 \times \frac{1}{5}$
hours, she completed
$\frac{3}{7}$
of her journey. What is the distance between Town X and Town Y ?

Please give me step by step explanation. ​

Answer 1

Answer:

Given ,

   speed, s = 78 km/hr

   Time = $1\frac{1}{5}$ hr

            = 6/5 hr

We know the formula,

     Distance = speed × time

Let  x be the total distance between town X and Y.

       $\frac{3}{7\\}$x = 78 × $\frac{6}{5}$

        x = $\frac{78* 6 * 7}{5 * 3}$

        x = $\frac{3276}{15}$

        x = 218.4 km
