Question

Set up the proportion for each problem and solve.

Maya can kayak 3 3/4 kilometers in 30 minutes. At this rate, how many kilometers can she kayak in 44 minutes?

Answer 1

5 1/2 km

Step-by-step explanation:

Let k represent the number of kilometers Maya can kayak in 44 minutes. Then the proportion is ...

`(3(3)/(4))/(30)=(k)/(44)`

This is solved by multiplying by 44, so ...

`k=(44\cdot 3(3)/(4))/(30)=(22)/(15)\cdot(15)/(4)\\\\=(11)/(2)=5(1)/(2)`

Maya can kayak 5 1/2 km in 44 minutes at the same rate.
