Answer:
Explanation:
1) for first 60min distance travelled speed*time
= 60*1= 60km
for next 1.5hrs
distance= 40*1.5= 60km
total distance= 120km
2) total time oftravel= 1+1.5= 2.5hrs
3) average speed ( <s> ) = tot dis/tot time
= 120km/ 2.5hrs = 48km/hr

Answer:
1. 120 km; 2. 2 hours 30 minutes; 3. 48 km/h. Pls mark me as brainliest.
Explanation:
In first part, Speed = 60km/h, Time = 60 min = 1h
Speed = Distance/Time, Distance = Speed x Time
Distance = 60km/h x 1h = 60km
In second Part, Speed = 40 km/h, Time = 1.5h
Speed = Distance/Time, Distance = Speed x Time
Distance = 40km/h x 1.5h = 60km
- Total Distance = 60km + 60km = 120km
- Total Time = 1h + 1.5h = 2.5h = 2h 30min
- Average Speed = Total Distance/Total Time
= 120km/2.5h = 48 km/h
