A bicycle increases its velocity from 10 km/h to 15 km/h in 6 seconds. Calculate its acceleration.

Dear student, 
bicyle's initial velocity is given as u=10km/h=50/18 m/s and finl velocity v=15km/h=75/18m/s
time t=6seconds
( 1km/h= 5/18 mps)

here a is the acceleration,
so, 75/18=50/18 + 6a
     75=50+ 108a
     a =0.23 m/s2
