During a science experiment, students measured that a toy car traveled 15 feet in 5 seconds. At this constant speed, how many yards could the car travel in a minute?



Answer :

To solve this problem step-by-step, follow these calculations:

1. Determine the speed of the car in feet per second:
- The car travels a distance of 15 feet in a time span of 5 seconds.
- Speed is calculated as distance divided by time.
- So, \( \text{Speed} = \frac{\text{distance}}{\text{time}} = \frac{15 \, \text{feet}}{5 \, \text{seconds}} = 3 \, \text{feet per second} \).

2. Calculate the distance the car travels in one minute (60 seconds):
- The car's speed is 3 feet per second.
- To find out the distance in one minute, multiply the speed by the number of seconds in one minute.
- So, \( \text{Distance in one minute} = 3 \, \text{feet/second} \times 60 \, \text{seconds} = 180 \, \text{feet} \).

3. Convert the distance from feet to yards:
- We know that there are 3 feet in a yard.
- To convert 180 feet to yards, divide the distance in feet by the number of feet per yard.
- So, \( \text{Distance in yards} = \frac{180 \, \text{feet}}{3 \, \text{feet/yard}} = 60 \, \text{yards} \).

Therefore, at this constant speed, the toy car could travel 60 yards in one minute.
