Given:
1 cm in the plan is equal to 2 meters in real life
Length of corridor in plan = 9 cm
To find:
Actual length of corridor
Steps:
Since we know that 1 cm in plan = 2 meters
So,
9 cm = 2 * 9
length of corridor = 2 * 9
Length of corridor = 18 meters
Therefore, the length of the corridor is 18 meters

Answer:
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.
