Question

What would be the usual time taken by Rajiv to drive home from the office, where today he was late by 50 Mins, driving 25 % slower than original speed, and started 30 Mins late?

Answer 1

Answer:

Actual time taken by late: 50 -30 = 20 minute

Ie: 20 minute late.

25% lower speed = 20 minute

By 25% low speed ,time taken to reach destination:

(20/25%) ×100 % ie: 80 minutes

Usually Ravi taken time reach office = by increasing 25% speed, 25% time reduced

Usually time taken : (75/100 )×80 = 60 minute

Ans : 60 minute.

Verification by low speed: 60 min. + 20 min. late = 80 min.

Low speed time taken above = 80 min.
