Answer 2

Answer:

Actual time = 64 min

Explanation:

Let v ( in m/min) be the fixed speed and t  (in min) be the corresponding actual time.

New speed = v - 0.2v = 0.8 v = 4v/5  m/s

New time = (t + 16) min

distance cocered in both cases are sme

    vt = 4v/5 x (t+16)

    5t = 4t + 64

      t = 64 min.
