Question

If there are 5,280 feet in every mile, then what is the speed of a car that is traveling 35 miles per hour in feet per second.

Answer 1

Hey there!

We see that we have 35 miles, and each one is 5,280 feet. Given this, we multiply them together and we see that we have 184800 feet per hour. But, we need feet per second. To do this, we can look at this.

60 seconds=1 minute

60 minutes= one hour

If we use this, we can see that there are 3600 seconds in one hour. We now divide our feet per hour divided by 3600 to get feet per second.

184800/3600= 51 1/3

Therefore, our answer is D) 51.

I hope this helps!

Answer 2

Answer:

d) 51

Step-by-step explanation:

5.280ft = 1 mile

5.280 x 35 = 184800 feet

184800/60 = 3080 per minute

3080/60 = 51.33 = 51

To check

35 mile = per hour we need to say every measure first = 35

35/60 = 0.583333...

0.583333 x 5280 = 3079.99824

3079.99824 = 3080/60 = 51

its 51

just to add; measure over time is how you could check.
