Question

A train is moving at a uniform speed of 84 km/hr.

(a) How far will it travel in 40 minutes?

(b) Find the time required to cover a distance of 250 km.​

Answer 1

Solution

Given :-

• S = 84 km/h

Find :-

• How far will it travel in 40 minutes
• the time required to cover a distance of 250 km.

Explanation

Using Formula

$\star\boxed{\underline{\tt{\red{\:Speed\:=\:\dfrac{Distance}{Time}}}}}$

Case 1.

Convert 40 min. in hours.

We know,

• 1 hour = 60 min

So,

• 40 min = 40/60 = 4/6 hours.

So, now use

• T = 4/6 hours

Keeo all above Values,

==> Distance = 84 × 4/6

==> Distance = 14 × 4

==> Distance = 56 km. [Ans]

______________________

Case 2.

Keep required values.

==> T = 250/84

==> T = 125/42

==> T = 3.38 hours. [ Ans]

Answer 2

Step-by-step explanation:

Solution

Given :-

S = 84 km/h

Find :-

How far will it travel in 40 minutes

the time required to cover a distance of 250 km.

Explanation

Using Formula

\star\boxed{\underline{\tt{\red{\:Speed\:=\:\dfrac{Distance}{Time}}}}}⋆

Speed=

Time

Distance

Case 1.

Convert 40 min. in hours.

We know,

1 hour = 60 min

So,

40 min = 40/60 = 4/6 hours.

So, now use

T = 4/6 hours

Keeo all above Values,

==> Distance = 84 × 4/6

==> Distance = 14 × 4

==> Distance = 56 km. [Ans]

Case 2.

Keep required values.

==> T = 250/84

==> T = 125/42

==> T = 3.38 hours. [ Ans]
