Question

Find the speed in M/sec. : distance = 60 km , time = 1 hr.

Answer 1

Speed = Distance/Time

Converting the distance and time into the units given.
That is, km into m
and hr into sec.

Distance :
→ 60 km = 60 × 1000 = 60,000 m

Time :
→ 1 hour = 60 × 60 = 3,600 s

So, speed = 60,000/3,600
= 16.66 m/s
≈ 16.7 m/s

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

Converting the distance and time into the

units given.

That is, km into m

and hr into sec.

Distance

60 km =60 x 1000 = 60,000 m

Time

1 hour = 60 x 60 = 3,600 s

So, speed = 60,000/3,600

=>16.66 m/s

=>$\bold{16.7\: m/s}$
