Answer:
A) 9 photos in each row
B) 14 rows in total
Step-by-step explanation:
Photos of People = 45
Photos of Landscapes = 18
Photos of Pets = 63
Jenny wants to arrange these photos in rows with only one kind of photos in each row and same number of photos in each row. We have to find the greatest possible number of photos in each row. For this we need to find the greatest common factor of 45,18 and 63. This would give us the greatest possible number of photos that can be placed in each row.
By observing the 3 numbers, we can tell that the greatest common factor of these 3 numbers is 9. So, Jenny can place 9 photos in each row.
So,
There will be:
45/9 = 5 rows with photos of people
18/9 = 2 rows of photos of landscapes
63/9 = 7 rows of photos of pets
So, total number of rows would be = 5 + 2 + 7 = 14 rows

Answer:
9
Step-by-step explanation:
The time required by the ambulance is ...
time = distance/speed
time = (20 mi)/(40 mi/h) = 1/2 h = 30 minutes
The time required by the helicopter is ...
trip time = takeoff time + route time + landing time
= (3 min) + (15 mi)/(1 mi/min) +(3 min) = (3 + 15 + 3) min = 21 min
The difference in times is ...
(30 min) -(21 min) = 9 min
The helicopter takes 9 fewer minutes for the trip.
