Question

A train travels 220km in 6hrs and 340km in 2 hrs .find the average speed of the train

Answer 1

In case 1 :-

In 6 hours train travels 220km

so, in 1 hour = 220/6 = 35 km

speed of train = 35km/h

In case 2 :-

In 2 hours train travels 340 km

So, in 1 hour = 340/2 = 170 km

speed of train = 170km/h

Now,

average speed of train = (170 + 35)/2

=> 205/2 = 102.5 km/h

Answer 2

Step-by-step explanation:

total distance traveled=220+340

=560km

total time taken=6+2

8hrs

average speed=560/8

= 70 km/hr
