Question

A commuter train travels 5252kilometers in 4545 minutes. What is its speed in kilometers per​ hour?

Answer 1

Answer:

The speed of the commuter train is approximately 69.333 Km/hr

Explanation:

Speed of the train can be calculated using the following rule:

$Speed = \frac{Distance}{Time}$

Note that the question requires the speed to be calculated in units kn/hour. Therefore, we should ensure proper units used

We are given that:

Distance covered by the train = 52 km

Time taken to cover this distance = 45 minutes which is $\frac{45}{60}=0.75$ hours

Now, we substitute with these givens in the above equation to get the speed of the train

This can be done as follows:

$Speed = \frac{52}{0.75} = 69.333$ Km/hr

Hope this helps :)
