Question

A bus starts from Aundh at 1pm and heads towards Swargate at a uniform speed. At 1:30pm, a car starts from Swargate and heads towards Aundh at a uniform speed. Somewhere along the way, the bus and car cross each other. Then, the bus reaches Swargate and the car reaches Aundh, both at 2pm. How many minutes had the car been traveling when it crossed the bus?

Answer 1

Answer:

The car had traveled 7.5 minutes when it crossed the bus.

Step-by-step explanation:

Step 1:  Let the distance traveled by car from uniform speed be d kilo meter in 1/2 hour=30 minutes  

Step 2: The distance traveled by the bus in 1/2 hour= d/2 kilo meter

Now time taken by the car to travel d/2 kilo meter= 30 minutes / 2=15 minutes

Step 3: Therefore 15/2 minutes the car had been traveling when it crossed the bus.
