Answer:
8miles
Step-by-step explanation:
If Brian jogged 2 miles in 30 minutes, this is expressed as;
2miles = 30minutes
To calculate the distance covered in 2hrs, we can say
x miles = 2hrs (120minutes)
Divide both expressions
2/x = 30/120
Cross multiply
30x = 2 * 120
30x = 240
x = 240/30
x = 8
hence he covers 8miles in 2hrs
