Question

One day, eesha started 30 minutes late from home and reached her office 50 minutes late, while driving 25%slower than her usual speed. How much time in minutes does eesha usually take to reach her office from home?

Answer 1

Answer:

here is little trick in the question.

she was 30 min late while coming out from home and reached 50 min late in office.

so time delay due to the slow speed is only (50-30) min

i.e 20 min not 50 min or any thing else.

so keep it in your mind.

Answer 2

let time taken by eesha daily = x

and usual speed = y

(x+20)*(.75*y) = x*y extra time taken = 50-30 = 20min

.75x+15 = x

.25x = 15

x = 60 min
