Question

Arjun walks from his house at 2½km/h and reaches his school late by 6 min. Next day, he increases his speed by 1km/h and reaches 6 min before school time . How far is the school from his house?​

Answer 1

Answer:

42

Step-by-step explanation:

first of All 2.5 km/h and reach late 6 min.

next day , (2.5+1)km/h= 3.5km/h and reach 6min soon.

Now total time 6+6= 12 min

and speed 3.5km/h

and formula distance= speed x time

Distance= 3.5x12=42.0
