A B
50 mph 60 mph
so let's recall that d = rt, distance = rate * time.
both cars start out at the same time, say "t" hours.
after "t" hours car A has covered say "d" miles, since there's a total of 1320, then car B must surely had covered the slack, or 1320 - d.
For both of them, $20 each is 40, so split 20, or if you meant 20 in total, split 10. 20% of 20 is 4, so 2. 20% of 40 is 8, so I have helped you no matter the problem. :)
Area of the figure
= (area of rectangle) + (area of triangle)
= (8 × 10) + (½ × 4 × 8)
= 80 + 16
= 96
Area = 96ft²
Quarts of paint needed
= 96/22
= 48/11
= 4.36
Mr. Chen will have to buy 5 quarts of paint.
Just add 8+8 12+12 then get your answer and multiply that by each number in the answer box until you get 192
Add 121 to 245 to get your answer.
the unit rate is 121, so you add 121 everytime
