Question Roxie and Estu overheard someone saying, “We did a padayatra for about 400 km to reach this place! We arrived early this morning.” How long ago would they have started their journey? Find answers by making necessary assumptions and approximations. Do guess first before calculating to check how close your guess was! (Page 34)
Guessing If someone walked 400 km on foot, how long might it take? Let us guess they walked about 25-30 km per day. ∴ Rough guess for number of days = 400 ÷ 25 = 16 days Or maybe 13-20 days, depending on speed and rest. Estimating and Calculating Let daily distance walked = 30 km Distance covered = 400 km Number of days = 400 ÷ 30 = 13.3 days ~ 13 to 14 days
