the time is in minutes
isn't it
so we have to convert min into sec
yes or just convert it into metre per minute
so 1/24 is correct

Given
initial velocity = 36 km/ hrs or 36 × 1000/60 m /min
= 600 m/ min
then
final velocity = 72km/hrs or 72×1000/60
= 1200m/min
as we know that
a = v-u/t
= 1200-600/4
= 600/4
= 150 m/min^2
initial velocity = 36 km/ hrs or 36 × 1000/60 m /min
= 600 m/ min
then
final velocity = 72km/hrs or 72×1000/60
= 1200m/min
as we know that
a = v-u/t
= 1200-600/4
= 600/4
= 150 m/min^2
this one is correct
