A snail travels 45 cm in 20 min. Its average speed is

Answer 2.25 cm/h.
15 cm/h.
90 cm/h.
135 cm/h.

45/20 = x/60

20x = 2,700

x = 135 cm/h

Well, it seems like that snail wasn't exactly breaking any land speed records, huh? I mean, 45 cm in 20 minutes? That's like watching a sloth on a coffee break. So, let's crunch the numbers: if we want to find the average speed in cm/h, we can divide the total distance traveled by the total time taken. In this case, 45 cm divided by 20 minutes gives us a speed of 2.25 cm/h. So, the correct answer is... drumroll please... 2.25 cm/h. Keep it slow and steady, little snail!

To calculate the average speed of the snail, we need to convert the time from minutes to hours and then divide the distance by the time.

First, we convert 20 minutes to hours by dividing it by 60:
20 min / 60 min/hour = 1/3 hour

Next, we divide the distance traveled by the time:
45 cm / 1/3 hour = 45 cm * 3 = 135 cm/hour

Therefore, the average speed of the snail is 135 cm/hour.

To determine the snail's average speed, you need to convert the given values to the same unit of measurement. In this case, we will convert minutes to hours and calculate the speed in cm/h.

Given:
Distance traveled = 45 cm
Time taken = 20 min

To convert minutes to hours, divide the time taken by 60 (since there are 60 minutes in an hour):

20 min / 60 = 0.3333 hours (rounded to four decimal places)

Now, divide the distance traveled by the time taken to find the average speed:

45 cm / 0.3333 hours = 135 cm/h (rounded to the nearest whole number)

Therefore, the snail's average speed is 135 cm/h.
