Answer: The answer is 3.
Step-by-step explanation: We are given to find the unit rate for 75% high-fibre chimp food to 25% high -protein chimp food.
For that, we need to divide the quantity of fibre in food by the quantity of protein present in the food.
Fibre present in the food is given by
And protein present in the food is
Therefore, the unit rate of high-fibre chimp food to high-protein chimp food is
Thus, the answer is 3.
Answer: you travelled 10 km
Step-by-step explanation:
Pam jogged up the hill at 6 km/h.
Let x represent the number of kilometers that you travelled by jogging up the hill or returning back.
Time = Distance/speed
Pam jogged up the hill at 6 km/h.
Time spent in jogging up the hill would be
x /6
She then jog back down the hill at 10 km an hour. Time spent in jogging down the hill would be
x /10
If the total jogging tie is 1 hour 20 minutes, converting to hours, it becomes 1 + 20/60 = 1.33
Therefore
x /6 + x/10 = 1.33
10x + 6x = 80
16x = 80
x = 80/16 = 5
Total distance travelled up and down the hill would b
5 × 2 = 10 km
