Question

A train covers 168 km in 4 hours. find its speed. How much distance it will cover in 80 minutes?​

Answer 1

Answer:

Step-by-step explanation:

Distance covered is 168 km .

Time taken is 4 hours .

Speed = distance covered / time taken

=168/4

=42 kmph

In 80 minutes or 4/3 hours it would cover

42*4/3

=14*4

=56 km

Answer 2

The speed of the train is 42 km/h and the train covers 56 km in 80 minutes.

Given : A train covers 168 km in 4 hours.

To find :

1. The speed of the train.
2. The distance that the train will cover in 80 minutes.

Solution :

We can simply solve this mathematical problem by using the following mathematical process. (our goal is to calculate the speed of the train and the distance covered by the train in 80 minutes)

Here, we will be using general arithmetic method.

So,

The train covers in 4 hours = 168km

The train covers in 1 hour = 168/4 = 42 km

Speed of the train = 42 km/h

Now,

In 1 hour the train covers = 42 km

In 60 minutes the train covers = 42 km (1 hour = 60min)

In 1 minute the train covers = 42/60 km

In 80 minutes the train covers = (42×80)/60 = 56 km

Hence, the speed of the train is 42 km/h and the train covers 56 km in 80 minutes.
