Question

Speed of a truck is 40 km/hr. Find the distance travelled by the truck in 240 minutes.`​

Answer 1

$\huge{\rm{Answer}}$

Speed of a truck = 40 km/hr

Time taken = 240 minutes

We know that, 1 hour = 60 minutes so, 1 minute would be equal to 1/60 hr.

240 minutes = 1/60 × 240 = 4 hrs.

Now, looking over the parameters

Speed = 40 km/hr ; Time = 4 hr

Distance travelled = ?

General Formula

Speed = Distance/Time

Distance = Speed × Time .

Distance = 40 × 4 = 160 km

Answer 2

★ Given :

Speed of a truck is 40 km/hr.

$\:$

★ To Find :

The distance travelled by the truck in 240 minutes ?

$\:$

★ Used Formula :

$\displaystyle \bf \: ⟹ \: S= \frac{D}{T}$

Where,

• S = Speed
• D = Distance
• T = Time

$\displaystyle \bf \red{⟹ \: Speed= \frac{Distance}{Time}}$

$\displaystyle \bf \red{⟹ \: Distance = Speed \times Time}$

$\:$

★ Solution :

Speed of a truck is 40 km/hr.

The distance travelled by the truck in 240 minutes is ?

We know that,

1 hour = 60mins

240 minutes = 1/60 × 240 = 4 hrs.

Here,

• Speed = 40km
• Time = 4hrs
• Distance = ?

So,

$\displaystyle \bf ⟹ \: Speed= \frac{Distance}{Time}$

$\displaystyle \bf ⟹ \: 40= \frac{D}{4}$

$\displaystyle \bf ⟹ \: Distance = Speed \times Time$

$\displaystyle \bf ⟹ \: D= 40 \times 4$

$\displaystyle \bf \red{ ⟹ \underline{\boxed{ \bf \: D= 160}}}$

Hence,

∴ ❝ The distance travelled by the truck in 240mins is 160km ❞
