Question

Mary started a four days walk covering 3.7 miles and approaches her home after a 6.7 mile. how many miles will it take Mary to cover 6 days walk?

Answer 1

We need to find the ratio miles to days in order to see how many miles she will cover in 6 days. This ratio is equal to

$\text{ratio}=\frac{3.7\text{ miles}}{4\text{ days}}=0.925\frac{miles}{\text{day}}$

that is, she walks 0.925 miles per day. Then, in 6 days, she will walk

$6\text{days}\times0.925\frac{miles}{days}=5.5\text{ miles}$

that is, she will walk 5.5 miles in 6 days.
