Question

how many minutes does a cover to take distance 400 meter if 20km speed
​

Answer 1

Answer:

13.3minutes

Step-by-step explanation:

We need to convert speed into m/s because in this question , we are going to take SI units for all quantities.

Speed= 20 × 5/18=0.5 m/s

We need to find time.

Time = distance/speed

Time= 400/0.5 =800 seconds

In this question we are being asked for time in Minutes and not in seconds. So let us convert 800 seconds into minutes.

1 second = 1/60 minute

800 seconds= 800 × 1/60 = 13.3 minutes.
