A car moves with a speed of 60 kmh for 30 min
and then at a speed of 30 kmh for the next 20 min
The foal distance covered by the car is

Answer 1

s=d/t

d=ts

3o min=1800 sec

d1=1800*60

d1=10800= metres=100.8 km

20 min=1200 sec

d2=30*1200

d2=36000

total distance =d1+d2

==>36000+108000

==>144000 metresor 144 km
