Question

Type the missing number to complete the proportion. 76 kilometers in 2 hours ABSENDE 38 kilometers in hours Submit

Answer 1

We can pose this proportion as follows:

$\frac{76k}{2h}=\frac{38k}{x}\Rightarrow\frac{2h}{76k}=\frac{x}{38k}\Rightarrow x=\frac{2h\cdot38k}{76k_{}}=\frac{2h\cdot1}{2}\Rightarrow x=1h$

Therefore, the answer to this value is x = 1 h.

We can check as follows:

$\frac{76}{2}=\frac{38}{1}=38$

The ratio is constant (38).
