Question

Edward runs with a speed of 3m/s. How long would it take him to run 1.2km? Give your answer in minutes to three significant figures.

Answer 1

`\bold{ANSWER:}`
6.67 mins


`\bold{SOLUTION:}`

To find the time it would take for Edward to run 1.2 km, we can use the formula:

Time = Distance / Speed

Given that Edward runs with a speed of 3 m/s and the distance is 1.2 km, we need to convert the distance to meters first.

1 km = 1000 m

Therefore, 1.2 km = 1.2 × 1000 m = 1200 m

Now we can calculate the time:

Time = 1200 m / 3 m/s = 400 s

To convert this time to minutes, we divide by 60:

Time in minutes = 400 s / 60 = 6.67 minutes

Rounding to three significant figures, the time it would take Edward to run 1.2 km is approximately 6.67 minutes.
