Question

The distance between Delhi and Agra is 200 km. If you can maintain an average speed of 90 km/hr for 120 km and 40 km/hr for the remaining distance, how much time will you take, on average, to reach Agra?

A) 3 hr 20 min
B) 3 hr 30 min
C) 4 hr 45 min

Answer 1

The average time taken to reach Agra is 3 hours and 20 minutes. Therefore, the average time to reach Agra is 3 hours and 20 minutes, which corresponds to option A) 3 hr 20 min.

Step-by-step explanation:

To calculate the average time taken to reach Agra, we need to find the total time taken for each part of the journey and then find the average. First, calculate the time taken for the first part of the journey:

• Distance = 120 km
• Speed = 90 km/h
• Time = Distance / Speed = 120 km / 90 km/h = 1.33 hours

Next, calculate the time taken for the second part of the journey:

• Distance = 200 km - 120 km = 80 km
• Speed = 40 km/h
• Time = Distance / Speed = 80 km / 40 km/h = 2 hours

Now, find the average time:

• Average time = (1.33 hours + 2 hours) / 2 = 3.33 hours

Therefore, the average time taken to reach Agra is 3 hours and 20 minutes (or 3.33 hours), which is option A.
