Answer:
Cycling Speed is 15km/hr
Step-by-step explanation:
Let the cycling speed of Peter be xkm/hr
His walking speed is (x-10km/hr)
Distance cycling is 2/3 x 30 = 20km
Distance walking 1/3 x 30 = 10km
Time taken in cycling = distance/ speed
Time = 20/x
This gives 20/x km/hr
Time walking is 10 / (x-10)
= 10/x-10) hrs
Total time = (20/x + 10/x+10)
Therefore 10/x+10/x-10 = 10/3
60(x-10)+30(x)=10x(x-10)
10x² - 190x+600=0
x²-19+60=0
x=<u>19±√361-240</u>
2
x=15 0r x =4
His cycling speed is 4
where is number 1 i dont see it

Step-by-step explanation:
Answer:
m+2n+2p=16 tokens or m+2(n+p)= 16 tokens
Step-by-step explanation:
First, we must understand how many tokens they have.
Janie played the 3-token game four times, so she used 12 tokens (3n x 4 = 12). Jasmine played the 4-token game five times, so she used 20 tokens (4p x 5 = 20).
Added up, the girls have 32 tokens (12+20 = 32 tokens (t)).
In order to play a round of the three games, 9 tokens are required (m+n+p = 9 / 2+3+4 = 9) by each girl. (32t-18t=14) 14 tokens are left after taking a ride in every game each. 14 left divided by 2 will leave 7 more tokens for each girl. You can split these 7 tokens into an n+p = 7 tokens
Thus,
Each girl can ride as follows:
m+2n+2p=16 tokens or m+2(n+p)= 16 tokens
