Answer:
It will take 1.47 hours for the horse and clown to collide
Step-by-step explanation:
They are driving toward each other, in opposite directions.
So to find their speed of approximation, we add their speeds.
19 mph + 15 mph = 34 mph.
This means that each hour, they are 34 miles closer.
How long it takes for them to find each other if they are 50 miles apart?
1 hour - 34 miles
x hours - 50 miles
It will take 1.47 hours for the horse and clown to collide
Answer:
Step-by-step explanation:
We khow that A is the sum of all odd numbers that are less than 100
So A= 1+3+5+...+99
We can calculate this sum without adding all this numbers one by one
A = the number of terms *( first term + last one ) over 2
To get the number of terms we substract the first term from the last term then we add one
We khow that odd numbers are wiritten this way : 2*n +1 where n is an integer
So 99= 2*49+1
1= 2*0+1
So the number of terms is : 49-0+1 =50
So A= 50*(1+99)/2 = 2500
Foloowing the same method we get :
B= (49-1+1)*(2+98)/2= 2450
