Question

a car travels 400m in 8m/s and 1200m in 10ms and 360 m in 12m/s find average speed​

Answer 1

Answer:

here, d1=400m,d2=1200m,d3=360m

s1=8s,s2=10s,s3=12s.

.:. average speed = total distance/total time required.

400+1200+360/8+10+12

= 1960/20

= 98m/s

.:. The car travels with an average speed of 98m/s.
