The complete question is
<span>Sarah rides her horse for 2 1/6 hrs with a constant speed of 6 km/hr and then for another 2 hours and 5 minutes with a constant speed of 12 km/hr what is her average speed for the total trip?</span>
we know that
speed=distance/time
1) Sarah rides her horse for 2 1/6 hrs with a constant speed of 6 km/hr
time=2 1/6 hrs----> 13/6 hrs
speed=6 km/h
distance=speed*time----> 6*(13/6)---> 13 km
2)for another 2 hours and 5 minutes with a constant speed of 12 km/hr
time=2hrs+5 minutes----> 2+(5/60)--> 125/60 hrs
speed=12 km/hrs
distance=speed*time----> 12*(125/60)---> 25 km
3) find the average speed for the total trip
total distance=13 km+25 km----> 38 km
total time=(13/6)+(125/60)----> (10*13+125)/60----> 4.25 hours
speed=38/4.25----> 8.94 km/hrs
the answer is
8.94 km/hrs

Answer:
96M&M's
Step-by-step explanation:
Given
Probability of picking a Red M&M = 1/2
Probability of picking a Green M&M = 1/2 of 1/2 = 1/4
Since;
Probability = number of possible outcome/total outcome
For green;
Total green(possible outcome) = 24
Probability of choosing green = 1/4
Substitute into the formula;
1/4 = 24/Total outcome
Cross multiply
Total outcome = 4×24
Total outcome = 96
Hence there are 96 M&M's altogether
