how do i find the unit rate of 6. bike 21 km in 50 min
7. earn $18 for 1 hr 15 min work
8. sew 9 curtain panels in 15 days
9. Wyatt spent of his money on a train set and on tickets to a
play. He now has $18. How much money did Wyatt start with?
Explain why you chose the method you did.
How can you explain why you chose a particular method, if we provide the method?
This assignment is to get YOU to think about the processes involved. Good luck!
To find the unit rate in each scenario, we need to determine the amount per one unit of time or quantity. Here's how you can calculate the unit rate for each situation:
6. To find the unit rate for biking, divide the total distance (21 km) by the total time (50 min). So, the unit rate would be 21 km / 50 min.
7. To find the unit rate for earning money, divide the total earnings ($18) by the total time worked (1 hour 15 minutes). Convert the time to a fraction of an hour by dividing the minutes by 60 and adding it to the number of hours. Then, divide the earnings by this value.
8. To find the unit rate for sewing curtain panels, divide the total number of curtain panels (9) by the total number of days (15). So, the unit rate would be 9 curtain panels / 15 days.
9. To find out how much money Wyatt started with, we can use the concept of percentages. Let's say Wyatt spent x percent of his money on a train set and y percent on tickets. We can represent this as x% + y% = 100%. If he currently has $18 left, then the amount of money he spent would be 100% - (x% + y%). We can then set up an equation and solve for x% + y%.
In this case, we don't have the specific percentages, so we cannot calculate the exact initial amount. We would need additional information or assumptions to find the starting amount of money.
These methods were chosen based on the given information and the common approach for determining unit rates and solving equations involving percentages.
