Question

35/2km in 5hours. find speed in meter/ second.

Answer 1

hey there...

here is ur answer. ^ ^

the standard of the speed is M/S m/s meters / seconds.

the distance given is 35/2 and the time is 5 hours. .

then the speed will be

35/2/5

which is

$\frac{35}{2} \times \frac{1}{5}$

which is

$\frac{35}{10}$

so the speed is

3.5 km / hr .....

now let's convert this into m/s

we need to multiply km with 1000 and hr with 3600

1000 becoz 1 km is 1000m
3600 becoz 1 hr is 3600 sec.


$\frac{3.5}{1} \times \frac{1000}{3600}$

let's simply 1000 and 3600 we will get....

$\frac{5}{18}$
so....

$\frac{3.5}{1} \times \frac{5}{18}$

we get

$\frac{17.5}{18}$

so the answer is

$\frac{17.5}{18} \frac{m}{s}$


hope this helps!
