The difference in speed of the two cars is 72-60 = 12 km per hour.
The time they would be 8 km apart would be 8/12 = 2/3 of an hour
1 hour = 60 minutes
60 minutes x 2/3 = 40 minutes.
The cars will be 8 km apart in 40 minutes.
Answer:
After 40 min they will be 8km apart
Step-by-step explanation:
Car A is traveling 1km per minute Car B is traveling 1.2km per minute, so Car B will gain 1km on Car A every 5 min. To be 8km apart, you calculate 5min x 8 = 40 min
