Answer:

18km/h, 90km/h, 72km/h, 45km/h, 108km/h, 115.2km/h

Step-by-step explanation:

Multiply them by 5/18.

Answer 2

Given : The given measurements are -

1. 5 m/s
2. 25 m/s
3. 20 m/s
4. 12.5 m/s
5. 30 m/s
6. 32 m/s

To find : To convert the given measurements into km/h unit.

Solution :

We can simply solve this mathematical problem by using the following mathematical process.

First of all, we have to establish the mathematical relationship between m/s and km/h, for easier calculation.

So, if something covers -

In 1 second = 1 metre

Then it will cover -

In 3600 seconds = 3600 metres

In 1 hour = 3.6 km

(As, 3600 seconds = 1 hour ; 1000m = 1 km)

So,

1 m/s = 3.6 km/h

Similarly,

• 1 m/s = 3.6 km/h
• 5m/s = 3.6 × 5 = 18 km/h

• 1 m/s = 3.6 km/h
• 25m/s = 3.6 × 25 = 90 km/h

• 1 m/s = 3.6 km/h
• 20 m/s = 3.6 × 20 = 72 km/h

• 1 m/s = 3.6 km/h
• 12.5 m/s = 3.6 × 12.5 = 45 km/h

• 1 m/s = 3.6 km/h
• 30 m/s = 3.6 × 30 = 108 km/h

• 1 m/s = 3.6 km/h
• 32 m/s = 3.6 × 32 = 115.2 km/h

Hence, 5 m/s is equal to 18 km/h , 25 m/s is equal to 90 km/h , 20 m/s is equal to 72 km/h , 12.5 m/s is equal to 45 km/h , 30 m/s is equal to 108 km/h , and 32 m/s is equal to 115.2 km/h.
