Speed of Sam = Distance / Time
Here, Distance = 1 Km
Time = 1/3 hour
Substitute the values, in the formula:
Speed = 1 / 1/3 = 3 Km/h
Now, In next situation, Speed = 3 Km/h
& Time = 4/5 hour.
Substitute the values, in the same formula:
Distance = Speed × Time
D = 3 * 4/5
D = 12/5 = 2.4 Km
In short, Final answer of your question would be 2.4 Km
Hope this helps!

Answer:
first check the smallest number that divide 784
i.e 2
784/2 = 392/2= 196/2 =98/2 =49/7=7
we get
748= 2*2*2*2*7*7
for square root take one out of 2 same number
square root of 784= 2*2*7 = 28
Answer: D
Step-by-step explanation: Quadrant 3 i (negative, negative)
This question is based on combinations
Out of 7 appetizers, 4 are to be selected, this becomes = 7C4
Out of 3 main courses, 2 are to be selected , this is = 3C2
Out of 5 desserts, 4 are to be selected, this is = 5C4
So, total ways become =
7C4 * 3C2 * 5C4
7!/4!(7-4)! * 3!/2!(3-2)! * 5!/4!(5-4)!
= 35*3*5 =525 ways
Hence, this can be done in 525 ways.
