Spencer wants to burn 450 calories while biking. Biking burns about 10 calories per minute. When Spencer goes biking, he usually plans to stop and rest for about 15 minutes.
Complete the equation below to find the total number of minutes (including rest) that Spencer should plan to be out biking. Use m to represent the total minutes.
10m + 15 = 450
To find the total number of minutes (including rest) that Spencer should plan to be out biking, we can set up an equation.
Spencer burns about 10 calories per minute while biking. Let's assume he bikes for a total of m minutes, including rest.
During the m minutes of biking, Spencer would burn 10 * m calories.
However, during the rest period of 15 minutes, Spencer is not burning any calories.
Therefore, the total number of calories burned should be equal to 450 calories.
10 * m + 0 * 15 = 450
Simplifying the equation:
10m + 0 = 450
10m = 450
Finally, to find the total number of minutes (including rest), we divide both sides of the equation by 10:
m = 450 / 10
m = 45
So, Spencer should plan to be out biking for a total of 45 minutes (including the 15-minute rest period).
To find the total number of minutes (including rest) that Spencer should plan to be out biking, we can set up an equation.
Let's say the time Spencer spends biking without rest is represented by t.
The total time Spencer spends biking, including rest, is t + 15 minutes.
Since Spencer burns about 10 calories per minute while biking, the total number of calories burned while biking is given by:
10 * t
According to the problem, Spencer wants to burn 450 calories while biking. Using this information, we can set up the equation:
10 * t = 450
Now, we can solve this equation for t to find the time Spencer spends biking without rest:
t = 450 / 10
t = 45
Thus, Spencer should plan to be out biking for a total of t + 15 = 45 + 15 = 60 minutes.
