It took Marlo 42 minutes to walk 3 miles. It took his sister 72 minutes to walk 6 miles. If the ratio of minutes to miles is constant for each person, how much longer will it take Marlo to walk 9 miles than his sister?

Sagot :

It would take Mario 18 minutes longer than his sister

Calculating Time

From the question, we are to determine how much longer it would take Mario to walk 9 miles than his sister

First, we will determine the speed of each one of them

Using the formula,

Speed = Distance/ Time

Mario's speed = 3 miles/ 42 minutes

Mario's speed = 1/14 miles/ minute

and

His sister's speed = 6 miles/ 72 minutes

His sister's speed = 1/12 miles/ minute

Now, we will determine how long it would take each one of them to walk 9 miles

Using the formula,

Time = Distance / Speed

For Mario,

Time = 9 ÷ 1/14

Time = 9 × 14

Time = 126 minutes

For his sister

Time = 9 ÷ 1/12

Time = 9 × 12

Time = 108 minutes

Difference in time = 126 minutes - 108 minutes

Difference in time = 18 minutes

Hence, it would take Mario 18 minutes longer than his sister
