Question

numericals based on velocity and average velovity​

Answer 1

I cant put ans for 90th question as I can upload only 2 pics. But here is the continuation.

Time= 0.5h + 1h + 2h= 3.5 h

Distance= (30 × 0.5) + (25 × 1) + (40×2)

= 15 + 25 + 80 =120km

Average speed = 120km/3.5h = 34.28km/h

Hope this helps.

Pls follow me and mark this answer as brainliest.
