73 feet per second
Steps-
Miles to cover- 50 miles = 50*5280 feet = 264,000 feet
Time it takes- 1 hour = 1*60*60 seconds = 3,600 seconds
So speed is- 264,000 feet per 3,600 seconds = 264,000 / 3,600 = 73.33 ft per second
Answer: 54.4 mph
Step-by-step explanation:
First find the distance to the train station. If it took Carlos 4 hours to come back driving at 68 mph, the distance is:
= Speed * time
= 68 * 4
= 272 miles
This means that Carlos drove for 5 hours to cover 272 miles the first time. His average speed was therefore:
= Distance / time
= 272/5
= 54.4 mph
Answer:
384 cm
Step-by-step explanation:
7.5 x 24 = 180
8.5 + 7.5 = 16
16 x 24 = 384
Answer:
Yes, they are equivilant
Step-by-step explanation:
5(3m+2p)-4m = 13p+11m-3p
Distribute 5: 15m+10p-4m = 13p+11m-3p
Combine like terms: 15m+(-4m) = 11m ; 13p+(-3p) = 10p
11m+10p = 11m+10p
