Respuesta :

Answer:

Amy has to wait 0.5 minutes per mile for Sebastian to arrive.

Step-by-step explanation:

Given:

Amy can ride bike 4 miles = 30 minutes

Sebastian can ride bike 3 miles = 24 minutes

We need to find time required by one to wait for another to arrive.

Solution;

First we will find the unit rate for both;

For Amy;

4 miles = 30 minutes

1 miles = Number of minutes required to ride 1 mile.

Using Unitary method we get;

Number of minutes required to ride 1 mile = [tex]\frac{30}{4}=7.5\ mins[/tex]

For Sebastian :

3 miles = 24 minutes

1 miles = Number of minutes required to ride 1 mile.

Using Unitary method we get;

Number of minutes required to ride 1 mile = [tex]\frac{24}{3}=8\ mins[/tex]

From above we can see that;

Amy ride 0.5 minutes per mile faster than Sebastian.

Hence Amy has to wait 0.5 minutes per mile for Sebastian to arrive.
