Question

The distance travelled by car C is 50 m and the time taken is 3.6 seconds. Estimate the time,in minutes, for car C to travel 5000m​

Answer 1

Answer:

6 minutes

Explanation:

Given:

Distance travelled by car c = 50m

Time taken by car C to travel 50 m = 3.6 seconds

To find:

Time (in minutes) for car C to travel 5000 metres

First let us find the speed of the car

Speed = $\frac{Distance}{Time}$

Speed = $\frac{50}{3.6}$

Speed = $\frac{500}{36} =\frac{125}{9} m/s$

Now distance = 5000 metres and speed = $\frac{125}{9} m/s$

Time = $\frac{Distance}{Speed}$

Time = $\frac{\frac{5000}{125} }{9}$

Time = $\frac{5000}{125} \times 9$

Time = $40 \times 9$

Time = 360 seconds

60 seconds = 1 minute

360 seconds = 6 minutes

6 minutes is the time taken

Answer 2

Time taken by car C to travel 5000 m is 6 minutes.

Solution

We have distance travelled by car C is 50 m, time taken is 3.6 seconds.

We know that,

● Distance = Speed × Time

⇒ 50 = Speed × 3.6

⇒ Speed = 50/3.6

⇒ Speed = 13.89 m/s

Now we have distance = 5000 m, speed = 13.89 m/s

We will find time taken to travel 5000 m.

☢ Using speed formula :

● Distance = Speed × Time

⇒ 5000 = 13.89 × Time

⇒ Time = 5000/13.89

⇒ Time = 360 seconds

⇒ Time = (360/60) minutes.

⇒ Time = 6 minutes.

∴ Time taken by car C to travel 5000 m = 6 minutes. (Answer)
