Answer» If V(average) = 36km/h Then initial speed, is V. Final Speed is, V+15. V(average) = 36 = (V + V + 15)/2 72 = 2V + 15 2V = 57 V = 28.5 km/h (initial speed) V + 15 = 43.5 km/h (final speed)

Answer»

If V(average) = 36km/h

Then initial speed, is V.

Final Speed is, V+15.

V(average) = 36 = (V + V + 15)/2

72 = 2V + 15

2V = 57

V = 28.5 km/h (initial speed)

V + 15 = 43.5 km/h (final speed)
