guys its urgent please send fast chapter motion​

Answer 1

Answer:

s=1/2 (u+v)t

Here s= distance, v= final velocity, u=initial velocity and t=time interval

Given , v=80 Km/h, u=20 Km/h, t=4 minute = 4/60 hour = 1/15 hour

Solution:

s (distance/displacement) = 1/2 (u+v) t

s=1/2 (20 Km/hour + 80 Km/hour) × 1/15 hour

=1/2 ×100 Km/h × 1/15 hour

=50 Km/hour × 1/15 hour

= 3.33 Km (Answer)
