It rained 464 inches in the rainforest in the last 2 years. On average, how much rain fell in 1 year?
To find the average amount of rain that fell in 1 year, we need to divide the total amount of rain that fell in the last 2 years by 2.
464 inches ÷ 2 = 232 inches
Therefore, on average, 232 inches of rain fell in 1 year.
A painter can paint 375 square feet in 3 hours. At this rate, how many square feet can he paint in 7 hours?
To find out how many square feet the painter can paint in 7 hours, we need to determine the painting rate per hour first.
Square feet per hour = Square feet ÷ Hours = 375 square feet ÷ 3 hours = 125 square feet per hour
Next, we multiply the square feet per hour by the number of hours the painter works for to find the total square feet painted.
Total square feet painted = Square feet per hour x Hours worked = 125 square feet per hour x 7 hours = 875 square feet
Therefore, the painter can paint 875 square feet in 7 hours.
A scientist is growing bacteria in a beaker. At this rate, in 4 hours, 122 bacteria have grown. How many bacteria will grow in 6 hours?
To find out how many bacteria will grow in 6 hours, we need to determine the growth rate per hour first.
Bacteria per hour = Bacteria ÷ Hours = 122 bacteria ÷ 4 hours = 30.5 bacteria per hour
Next, we multiply the bacteria per hour by the number of hours to find the total bacteria grown.
Total bacteria grown = Bacteria per hour x Hours = 30.5 bacteria per hour x 6 hours = 183 bacteria
Therefore, in 6 hours, 183 bacteria will have grown.
To find out how much rain fell on average in one year, you need to divide the total amount of rain that fell in the last 2 years by 2.
So, to get the average amount of rain in one year, you would do:
464 inches / 2 years = 232 inches
Therefore, on average, 232 inches of rain fell in the rainforest each year.
