To find a speed in miles per hour, we need to divide a number of miles by a number of hours.
We are given 48 miles, so we already have a number of miles.
We are given the time as 1 hour and 12 minutes. We need to convert this time into hours.
1 hour + 12 minutes = 1 hour + 12/60 hour = 1.2 hours
speed = distance/time = 48 miles / 1.2 hours = 40 mph
Answer: The fourth choice, 40 mph.

Answer:
v=2 s=5
Step-by-step explanation:
a) v=volleyball s=soccer
s × v = 7
" the soccer (s) practice lasts 1 hour (1) more than (+) twice as long (2) as the volleyball (v) practice; this simplifies to: s = 1 + 2v
b) substitute equation for soccer for s
(1 + 2v) + v = 7
solve for v
1 + 3v = 7 (2v + v = 3v; that's where the 3v comes from)
we subtract 1 from both sides
3v = 6
we divide 3 from both sides
v=2
solve for s
since we know what v equals, we substitute it in
s + 2 =7
subtract 2 from both sides
s = 5
