Question

Raja walks 1 1/2 meters in 1 second. How much distance will he walk in 15 minutes?

Answer 1

Distance walked=1.5 m
Time taken=1 sec
So, its speed is 1.5 m/s
(Speed=distance/time)
Now, time= 15 min=900 sec
(1 min=60 sec)
so, distance travelled=speed x time
=1.5 x 900
=1350 m

Answer 2

distance,= 3/2 m , t= 1 sec
speed= distance/ time
speed== (3/2)/1
speed =3/2 m/s

time = 15min
time = 15×60= 900sec. ( 1min= 60sec)
distance=speed× time
distance= 900× 15
distance= 13500 m
