IAM Pune Questions and Answers

Dear student,

Here's how you calculate the average speed of the car

1. Calculate the total distance traveled:

Distance 1 = 39 km

Distance 2 = 25 km

Total Distance = Distance 1 + Distance 2 = 39 km + 25 km = 64 km

2. Calculate the total time taken:

Time 1 = 45 minutes

Time 2 = 35 minutes

Total Time = Time 1 + Time 2 = 45 minutes + 35 minutes = 80 minutes

3. Convert the total time to hours:

There are 60 minutes in an hour.

Total Time in hours = 80 minutes / 60 minutes/hour = 80/60 hours = 4/3 hours

4. Calculate the average speed:

Average Speed = Total Distance / Total Time

Average Speed = 64 km / (4/3) hours

Average Speed = 64 * (3/4) km/hour

Average Speed = (64 * 3) / 4 km/hour

Average Speed = 192 / 4 km/hour

Average Speed = 48 km/hour

Therefore, the average speed of the car is 48 km/hour.
