A train covers 1.2 km in 1 minute. How far will it travel in 2 hours 15 minutes?

Correct Answer: 162 km

To find the total distance traveled by the train in 2 hours 15 minutes, we can calculate the distance step-by-step using unit conversion and basic speed-distance formulas.

Step 1: Convert the total time into minutes.
We know that 1 hour = 60 minutes.
So, 2 hours = 2 × 60 = 120 minutes.
Adding the remaining 15 minutes:
Total time = 120 minutes + 15 minutes = 135 minutes.

Step 2: Calculate the total distance.
The train covers 1.2 km in 1 minute.
To find the distance covered in 135 minutes, we multiply the speed (distance per minute) by the total time in minutes:

$\text{Distance}=1.2\text{ km/min}\times 135\text{ min}$

$\text{Distance}=162\text{ km}$

Thus, the train will travel a total distance of 162 km in 2 hours 15 minutes.
