Answer:
25km/h
Explanation:
this question involves the application of the first equation of motion
v=u+at
Where v= final velocity
u=initial velocity
a = acceleration
t= time
v=? u=10km/h t=30mins =0.5h (half an hour) a=30km/h/h
therefore, v= 10 + (30 ×0.5)
v=10 +15
v=25km/h
note that time was converted to h so that the units in the question would be uniform
