The answer to your question is 3
First, convert the distance of a typical marathon to kilometers.
1 mi = 1.609 km
26.2 miles = 42.165 km
Divide this distance by Allan's average speed to get his average time.
42.165 km / 12 km/hr = 3.514 hours
14 + 5(x+3)-7
14 + 5x +15 -7
5x + 22
I believe that x=20 from the math i did hopefully its helpful.
Answer:
$14
Step-by-step explanation:
$20 minus the $6 she came back with equals $14, which is what she spent.
(20-6=14)
