Question

The velocity of car is 10 m/s. It is equivalent to ...

Answer 1

Distance travelled=1 KM or 1000 meter (SI Unit)Velocity=10m/s

Now as you know time is equal to distance travelled per unit Velocity.

.•. Time=1000m/10(m/s) = 100 sec. or 1.667 minutes.

Answer 2

Answer:

This velocity is equivalent with 36 km/hour , 22.356 miles/hour and 19.438 knots/hour .

Explanation:

Provided that:

The velocity of car in meter/sec unit :

v = 10 m/s

In Km/hour unit;

$v = 10 \: m/sec \\ = (10 \times 3600) \: m/3600 \: sec \\ = 36000 \: m/hour \\ = 36 \: km/hour$

So we get the velocity of car that is 36 km/hour .

Now in miles/hour unit;

$v = 36 \: km/hour \\ = (36 \times 0.621) \: miles/hour \\ = 22.356 \: miles/hour$

So we get velocity of car that is 22.356 miles/hour .

Now for ships or submarines we use nautical miles/hour unit to measure velocity.

So now in knots/hour unit;

$1 \: k m = 0.539957 \: knots \\ \\ v = 36 \: km/hour \\ = (36 \times 0.539957) \: knots/hour \\ = 19.438 \: knots/hour$

So we get velocity of car that is 19.438 knots/hour .
