Answer:
302.5 km
Step-by-step explanation:
Distance = Speed × Time
In first half of the time
d1 = 30 kmph × 11/2 h = 165 km
In next half of the time
d2 = 25 kmph × 11/2 h = 137.5 km
Total distance = 165 km + 137.5 km = 302.5 km

Hola !
Average speed for first half
= Total time taken /Distance traveled
=30/11
Average speed for second half = 2s /11×30/11
=>2s=30
=s=15.
Total distance traveled by car =2s
=2×15
=30 km
