2 answers:
44ft/sec = 44/5280 divided by (1/3600 = 30 miles per hour <span>
Distance traveled in 5 hrs = speed * time = 30 * 5 = 150 miles </span>
44 feet. 3600 seconds. 1 mile

1 second 1 hour. 5280 feet
I wrote it this way so the units cancel out. You are multiplying the fractions by each other
The car is going 30 mph, and will go 120 miles in 4 hours.

Answer:
325 miles
Step-by-step explanation:
$20 for each day
5 days
$0.30 for each mile
20(5) + 0.3x = 197.5
100 + 0.3x = 197.5
100 - 100 + 0.3x = 197.5 - 100
0.3x = 97.5
x = 325
If $600=6 tons
$600=6*2000
$600=12,000
12000/$600=$20
It’s $20 per pound
