The train 'A' travelled a distance of 120km in 3hrs whereas another trains 'b' travelled a distance of 180 km in 4hrs . which train travelled faster
Answers
Explanation:
▶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 =120/3
= 40 km/hr.
Now ..
▶Distance covered by 2nd train = 180 km
Time Taken = 4hrs.
Speed = 180/4
= 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.
Given:-
- Distance travelled by train 'A' (d₁) = 120km
- Time taken (t₁) = 3hrs
- Distance travelled by train'B' (d₂) = 180km
- Time taken (t₂) = 4hrs
To Find:-
- Which train travelled faster .
Solution:-
As we know that
→ Speed = Distance/Time
Speed For train 'A'
→ S = d/t
→ S₁ = d₁/t₁
Substitute the value we get
→ S₁ = 120/3
→ S₁ = 40km/h --------------------(i)
∴ The speed of train 'A' is 40km/h
Now ,
Speed For Train 'B'
→ S₂ = d₂/t₂
→ S₂ = 180/4
→ S₂ = 45km/h -------------------------(ii)
∴ The speed of train 'B' is 45km/h
Comparing equation (i) & (ii) we get
The speed of train'B' is higher than the speed of train 'A'
∴ The Train 'B' travelled faster
