Sagot :

Parrain

Answer: 0.474 miles

Step-by-step explanation:

First find out how fast they can run per minute.

Phil runs 3/8 miles in 7 minutes:

Speed = Distance / Time

= 3/8 ÷ 7

= 0.0536 miles/minute

Joe runs 5/8 miles in 9 minutes:

Speed = 5/8 ÷ 9

= 0.0694 miles per minute

In 30 minutes, Phil will run:

= Miles per minute * Time

= 0.0536 * 7

= 1.608 miles

Joe will run:

= 0.0694 * 30

= 2.082 miles

Difference:

= 2.082 - 1.608

= 0.474 miles
