Question

Edward runs with a speed of 3m/s. How long would it take him to run 2km? Give your answer in seconds to four significant figures.

Answer 1

Answer:

It will take 666.7 seconds for him to complete 2 km run.

Explanation:

1 km → 1000 m

2 km → 2000 m

$\boxed {time =\frac{distance}{speed} }$

Here the distance is 2000 m and speed is 3 m/s

$\boxed {time = \frac{2000}{3} }$

$time = 666.666667$

$time = 666.7$ seconds _____in four significant figures.

Answer 2

$\huge\underbrace\mathrm\orange{ Answer}$

1 km = 1000 m

2 km = 2000 m

$time = \frac{distance}{speed}$

The distance is 2000 m and speed is 3 m/s

$time = \frac{2000}{3}$

$time = 666.666667$

So, 666.666667 seconds in four significant figures.
