Example 3. Two runners cover the same distance at the rate of 15 km/h and 16 km/h
respectively. Find the distance travelled when one takes 16 minutes more than the
other.
Solution: Let the required distance be x km.
Time taken by the first runner to cover x km at 15 km/h = “h
15
Time taken by the second runner to cover x km at 16 km/h = -h
16
Now,
=
x x – 16
15 16 60
(I don’t know
a I get 60 here)
or
16x – 15x 16
240 60
16×240 – 64
х
16
60
i.e., x =
or
240
60
.. The required distance is 64 km.​

  1. Answer:

    64 km

    Step-by-step explanation:

    Let the required distance be x km.

    Time taken by the first runner to cover x km at 15 km/h = “h

    15

    Time taken by the second runner to cover x km at 16 km/h = -h

    16

    Now,

    =

    x x – 16

    15 16 60

    (I don’t know

    a I get 60 here)

    or

    16x – 15x 16

    240 60

    16×240 – 64

    х

    16

    60

    i.e., x =

    or

    240

    60

    .. The required distance is 64 km.​
