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}*0.925(miles)/(days)=5.5\text{ miles}`

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