Max Steel drives his 1969 Mustang 15 miles per hour. If there are 5280 feet in one mile and 60 seconds in one minute, how many feet can he go per second? I need help I don't understand.
Oh ok thank you!
you can always multiply by 1 without changing anything. So, since
5280 ft = 1 mi,
5280ft/1mi = 1mi/5280ft = 1
So, use the values of 1 which cancel the unwanted units. That way you never have to wonder whether to multiply or divide, and by what.
15mi/hr * 5280ft/mi * 1hr/3600s = (15*5280/3600) ft/s
1 mile = 5 280 ft
1 h = 60 min = 60 ∙ 60 = 3 600 s
15 miles = 15 ∙ 5 280 = 79 200 ft
1 h = 3600 s
15 miles/ h = 15 mph = 15 ∙ 5 280 / 3 600 =
79 200 / 3 600 = 3 600 ∙ 22 / 3 600 = 22 ft / s
So 220 ft/s?
To find how many feet Max Steel can go per second, we need to convert miles per hour to feet per second.
First, let's convert miles into feet. We know that there are 5280 feet in one mile. So, to convert from miles to feet, we multiply the number of miles by 5280.
Max Steel's speed is given as 15 miles per hour. Therefore, we can calculate the total distance he can go in feet per hour by multiplying 15 miles by 5280 feet: 15 * 5280 = 79,200 feet per hour.
Next, we need to convert this to feet per second. Since there are 60 minutes in an hour and 60 seconds in a minute, there are 60 * 60 = 3600 seconds in an hour.
To convert from feet per hour to feet per second, we divide the number of feet per hour by the number of seconds per hour (3600 seconds): 79,200 feet / 3600 seconds = 22 feet per second.
Therefore, Max Steel can go 22 feet per second in his 1969 Mustang.
