Let +s+ = the speed of the bus
+1.5s+=+60+ km/hr is the speed of the car
+s+=+60%2F1.5+
+s+=+40+ km/hr
-------------------
For the car:
+72+=+60t%5B1%5D+
+t%5B1%5D+=+72%2F60+
+t%5B1%5D+=+1.2+ hrs
For the bus:
+72+=+40t%5B2%5D+
+t%5B2%5D+=+72%2F40+
+t%5B2%5D+=+1.8+ hrs
The bus takes +1.8+-+1.2+=+.6+ hrs longer
+.6%2A60+=+36+
The bus takes 36 minutes longer
