1.5 minutes.
Step-by-step explanation:
The relative speed at which the car behind travels compared to the other car is 90 - 70 = 20 km/hr.
The time taken to travel 500 m ( =0.5 km) is 0.5 / 20 = 0.025 hours.
= 0.025 * 60 = 1.5 minutes.
Answer: The first rule: am × an = am+n. 3. 3. The second rule: (am)n = amn. 3. 4. The third ... three a's at the bottom can be divided out, so we are now left with a4. 1 that is a4. The same answer is obtained by subtracting the indices, that is, 7 − 3=4.
