Answer 1

Answer:

oooo bahut hard hai sorrrryyyy

Answer 2

Answer:

Step-by-step explanation:

Let, usual speed = x

usual time = t

Then, distance (d) = speed * time = xt (i)

Again, new speed = 1/4x

new time = t+ 60

d = 1/4x ( t+ 60) (ii)

From (i) and (ii)

xt = 1/4x ( t + 60)

4xt = xt + 60x

4xt - xt = 60x

3xt = 60x

3t = 60

t = 20
