Answer:

125km/h

he drives car with the speed of 50km/h

means 50km in one hour

so in half of hour 30 mints

he drives his car 25km.. half of 50km

now speed=distance/time

distance=25km×30mints

according to question give time 12mints

so speed= 25×30/12

=750/12

= 62.5 constant speed in 12mints for 25km
