Answer 1

Answer:

Distance ¹ = 30km* 1/2 hr( converted into hr)

= 15 km/hr

Distance ² = 40km* 1hr

= 40 km/hr

(a) total distance = distance ¹ + distance ²

= 15 + 40 km/ hr

= 55km/hr

(b) total time = 1/2 + 1hr

= 3/2 hrs or 1.5 hrs

(c) average speed= total distance / total time

= (55km/hr) / (1.5hr)

= 36.67 km/hr
