Answer 1

Answer:

Speed of second car =53.33km/hr

Explanation:

Speed of first car =40km/h

Time taken by first car =4hrs

Distance covered by first car =Speed× Time

=40km×4hr

=160km

Distance covered by first car =Distance covered by second car

Time taken by second car =4hrs-hrs

=3hrs

Speed of second car =Distance ÷Time

=160km÷3hrs

=53.33km/hr
