Question

**MEDAL**
I'm making flashcards to help me with my ASVAB. Help me with some formulas?

Rachel ran ½ mile in 4 minutes. At this rate, how many miles can she run in 15 minutes?

A. 1 7/8 <--
B. 4
C. 30
D. 60

Formula?

Answer 1

That's dem military things ain't it?

Answer 2

Assuming Rachel doesn't get fatigued...

If she runs 1/2 mile in 4 minutes, then she is running 1/8 mile every minute (1/8 mile x 4 min = 4/8 = 1/2 mile per 4 min).

Now simply multiply the 1/8 mile by the 15 minutes she is running.

1/8 mile x 15 min = 15/8 = 1 and 7/8 or 1.875 miles

Answer 3

@NotTim The ASVAB? yeah. It's a required test prior to you joining.

Answer 4

v=d/t
where v is the speed in mile/minute, d is the distance in mile, and t is time in minutes.
so v=0.5/4=0.125miles/min
now you want to find distance.
so you rearrange the formula to isolate for d
d=vt
so now uk v=0.125mile/min and t=15
multiply them together and you get that answer but decimal form.

Answer 5

Thanks everyone! I wish I could give more then medal.
