given=
speed v=10ms-1
time t = 20min=20×60=1200s
therefore we know that
speed =distance/time
so., distance will be =speed ×time
=1200×10
120000=120km
speed v=10ms-1
time t = 20min=20×60=1200s
therefore we know that
speed =distance/time
so., distance will be =speed ×time
=1200×10
120000=120km

There are 60secs in a minute..
How much secs in 20 mins = 20×60 = 1200secs
Distance covered in 1sec = 10mtr
Distance covered in 1200secs = 10 × 1200 = 12000mtr
we know that, 1000mtr = 1km
total distance covered in 20mins = 12km
How much secs in 20 mins = 20×60 = 1200secs
Distance covered in 1sec = 10mtr
Distance covered in 1200secs = 10 × 1200 = 12000mtr
we know that, 1000mtr = 1km
total distance covered in 20mins = 12km
