Question

Shyam takes 15 minutes to reach his school. If he
walks at a constant speed of 7 km/h, then how far
is his school?
(1) 1.75 km (2) 2.5 km
(3) 1.5 km (4) 3 km

Answer 1

As speed is 7kmph, means
Shyam covers a distance of 7 km in 60 minutes
In 1 minute distance covered = 7/60km
In 15 minutes distance covered to reach the school(as given that Shyam reaches to school in 15 minutes)=7/60×15=7/4=1.75km
