please help me​

Answer 1

Answer:

Average speed 60 km

Distance travelled per minute is 1 km

Step-by-step explanation:

distance travelled in 1 hr = 50 km

distance travelled in 2 hrs = 50+60 km =110 km

distance travelled in 3 hrs = 50+60+90 km = 200 km

distance travelled in 4 hrs = 50+60+90+40 km = 240 km

speed = distance / Time = 240/4 =60 km

Distance travelle per minute = 60/60 = 1 km

Answer 2

Answer:

Step-by-step explanation:

Total distance travelled = 50+60+90+40=240km

Total time taken = 4hour

Average speed = Total distance travelled / Total time taken

=240/4 = 60km/hour
