Answer:
ans=43.2km
Step-by-step explanation:
as we know,distance=speed *time
in case 1,speed=40km/hr time =40 minutes=40/60 hrs
distance=40*40/60 =26.6 km
case 2, speed=50 km/hr time= 20 minutes=1/3 hrs
distance=50*1/3 = 16.6
total distance covered=distance in case 1 +distance in case 2
=26.6 km+16.6 km
=43.2 km

Answer:
1. speed=40km/hr
time =40 minutes=40/60 hrs
distance=40x2/3 (simplest form) =26.6 km
2. speed=50 km/hr
time= 20 minutes=1/3 hrs
distance=50x1/3 = 16.6
total distance covered=
