Answer:
60 kilometers per hour (kmph) over the limit
Step-by-step explanation:
The speed limit is 60 kmph
Let's find his original rate:
We know D = RT
Where
D is the distance, in km
R is the rate, in kmph
T is the time in hours
He went 10 km in 5 minutes, so we need the time in hours, first. That would be:
5/60 = 1/12 hour
So, putting into formula, we find rate:
D = RT
10 = R(1/12)
R = 10/(1/12)
R = 10 * 12
R = 120 kmph
He was going over by:
120 - 60 = 60 kmph
Answer:
18
Step-by-step explanation:
2:3 x 9
18:27
18 + 27 = 45
Answer:
x = 13
Step-by-step explanation:
(11x - 15) + (5x - 13) =180
16x -28 = 180
16x = 208
x = 13

Answer:
3) C
Step-by-step explanation:
The question is asking which pair is equal. Work through each problem to solve.
8(2r) and 10r
16r ≠ 10r
6r + 3 and 9r
6r + 3 ≠ 9r
9(3r - 4) and 27r - 36
27r - 36 = 27r - 36
r + r + r + r + r and r⁵
5r ≠ r⁵
