Use "converting units"
A snail moves at 0.5 cm per second. It travels at a constant speed around the 1.5 m perimeter of a planter. How long does it take the snail to complete its trip?
To solve this problem, we need to convert the units of distance from meters to centimeters so that we can compare it to the snail's speed in centimeters per second.
1.5 m = 150 cm (since 1 m = 100 cm)
Now we can use the formula:
time = distance ÷ speed
distance = 150 cm
speed = 0.5 cm/s
time = 150 cm ÷ 0.5 cm/s
time = 300 seconds
Therefore, it will take the snail 300 seconds to complete its trip around the planter.
To calculate the time it takes for the snail to complete its trip, we need to convert the perimeter of the planter from meters to centimeters and then divide it by the snail's speed.
Given:
Snail speed = 0.5 cm/s
Planter perimeter = 1.5 m
To convert meters to centimeters, we multiply by 100 because 1 meter equals 100 centimeters.
Planter perimeter in centimeters = 1.5 m * 100 cm/m = 150 cm
Now, we can calculate the time it takes for the snail to complete its trip by dividing the planter perimeter by the snail's speed.
Time = Planter perimeter / Snail speed
Time = 150 cm / 0.5 cm/s = 300 seconds
Therefore, it takes the snail 300 seconds to complete its trip around the planter.
