Can Someone Help Me With Thatnumbers 2345 I Need The Distance Time Andrate class=

Sagot :

2) I'm using r for rate .If it's 60km in 4h that means that 1/4=r/60 which means you can cross multiply it and it'd be 60=4r. If you divide 4 on both sides it would be 15=r. The rate is 15km and hour.

3) For this one, it's the same. You have to put 1/12=r/24 and cross multiply. It would be 24=12r then you divide both sides by 12 and you get 2=r.

4) It says d=r*t. For this problem, d=56 and r=8 if you substitute it you would have 56=8t and if you divide both sides by 8 you would have 7=t.

5) d=r*t. This means that if you substitute it, you would have d=25*160. 25*160=4000 so d=4000

The complete instructions are right above the problems in the picture.

"Substitute the information you know into the formula  d = r times t .
Then  solve the equation"

Nobody can say it any easier than that.

In #2, you know that  'd'  is  60km  and  't'  is  4 hours.
Substitute them into the formula  d = r times t

         60 km  =  'r'  times  (4 hours)

Divide each side of the equation by (4 hours):

         60km / 4 hours =  15 km/hour  =  ' r '

Don't make something hard out of something easy.
