Answers
Answer:
Distance is the length of the path covered by an object.
The distance travelled by a body per unit time is called speed.
In the following question we have to find out the speed of the train and compare that which train is faster.
⛧To find out the speed we have to use the formula .
speed = distance/time
So Distance covered by 1st train = 120 km.
Time taken =3 hrs
speed = 120km/3hr
= 40 km/hr.
Now ..
Distance covered by 2nd train = 180 km
Time Taken = 4hrs.
speed = 180km/4hr
= 45km/ hr
By comparison we have
45 km/hr >40 km /hr
So ,the train that travelled a distance of 180 km in 4 hrs had moved faster as compared to the train that travelled a distance of 120 km in 3 hrs.
