Jordan drives for three hours at an average of 60 miles per hour what is the distance in miles he drives during that time
1 answer:
Answer:
180 miles
Step-by-step explanation:
1. Use the drt (distance, rate, time) triangle (shown in the picture) to determine which operation you need to do.
You are given t (time) and r (rate), but you don't have d (distance). What you do is cover up the missing variable d (distance). Since you are left with t and r (time and rate), which are side by side, you multiply the numbers.
2. Plug in the numbers for t and r. Then multiply.
t=3
r=60
3 x 60 = 180 miles

Hello
I believe there is an error in the question
we have two equations and need to find x and y
let s multiply by 8 so that we can get rid of the fractions
(1) becomes 2x+4y=5
(2) becomse 6x-4y=9
if we sum it gives
2x+4y+6x-4y=9+5
8x=14
x = 14/8 = 7/4
and then from the first equation
4y = 5 - 7/4
<=> 16y = 20-7 = 13
y = 13/16
the solutions is (7/4,13/16)
