how did you do the math

Answer 1

Favorite Answer

The time, speed, distance relation is as under

Time = Distance/Speed

put in the two values you have and you will get the third.

Distance = 10 miles

Speed = 55 mph

Time = D/S = 10/55 hours = 10*60/55 minutes = 10.91 min.approx.

= 10 min and 55 seconds approx.

Hi:

Don't do the first answerer way he set it up wrong. The right way is

given :

r= 55mph, d= 10 ,t =?

slove for t

r*t= d - speed distance formula

1/r*r*t= d*1/r - Multiplying the the multiplicative inverse of a variable to both sides of the equation to move it to the other side of it

t= d/r - Multiplication

So :

10/55 = t - Substitution of d and r

0.18181818181818181818181818181818 hrs = t

0.181818181818* 60 = 10.909090... minutes or 10 minutes 55 seconds

Proof:

r*t= d - speed distance formula

55* .181818181818..= 10 - Substitution of t,d and r

9.99999999999999999 miles = 10 miles

this equals 10 this is one of those division that cannot exactly equal the number but it's close enough to say 10 mile here. Okay.

it checks and equals

I hope this helps

Answer 3

55=10x

solve for x
