Question

Answer 1

Answer:

hey mate

Explanation:

here is your answer

Data: v1 = 60 km/h S1 = 1 km v2 = 40 km/h s2 = 1 km

s = VT

T1 = S1/v1 = 1/60 h and T2 = S2/V2 = 1/40h

average speed of the car

= total distance/total time = S1 + S2/T1 + T2

1+1/1/60+1/60 = 2× 120/2+3

= 2× 120/5

= 2×24

=48km/h
