Question

50 m/ s to km/ hr change the following questions

Answer 1

Answer:

180km/hr

Step-by-step explanation:

Drill:

60seconds - 1 minutes(min)

60minutes - 1 hour(hr)

3600seconds - 1 hour(hr)

1000meters(m) - 1kilometres(km)

Back to the question,

50m/s could be written as

$\frac{50 \: \times \: 1m}{1s}$

We need to convert

1m to km

1s to hr

From

1000m = 1km

1m = 1/1000km

1m = 0.001km

From

3600s = 1hr

1s = 1/3600s

1s = 0.000278hr

Substitute the value for 1m and 1s in km and hr in ,

$\frac{50 \: \times \: 1m}{1s} \\ = \frac{50 \: \times \: 0.001km}{0.000278hr} \\ = 179.85 \frac{km}{hr} \\ = 180 \frac{km}{hr} \: approximately.....$

Thanks ❤.... Hope it helps
