Question

a speed limit of 100 kilometers per hour is approximately equal to 62 miles per hour. write an equation relating kilometers per hour , k to miles per hour , m. then predict to following measures round to the nearest tenth.

Answer 1

The relation between them is 1 km/hr=0.62 m/hr

Answer 2

Answer:

m = 0.6k

Step-by-step explanation:

If an object is traveling with the speed of k kilometers per hours or m miles per hour then relation between k and m can be represented by

$\frac{m}{k}=c$ where c is a constant.

Now we replace the values of k = 100 km per hour and m = 62 miles per hour to calculate the value of the constant k.

$\frac{62}{100}=c$

c = 0.62 ≈ 0.6

Therefore, the equation will be $\frac{m}{k}=0.6$

Or m = 0.6k

1 kilometer per hour = 0.6 miles per hour
