Question

Christy is training for a race in the summer. Every day she jogs the same number of miles. She also rides her bicycle 7.5 miles each day. During a 5-day training period, she jogs and rides a total of 53 miles. How many miles does Christy jog each day during training? Explain how you solved the problem.

Answer 1

Christy jogs 45.5 miles each day during training.

Step-by-step explanation:

To find out how many miles Christy jogs each day during training, we need to subtract the distance she rides her bicycle each day from the total distance she covers in the 5-day training period. Let's denote the number of miles she jogs each day as 'x'.

Given that she rides her bicycle 7.5 miles each day and in the 5-day training period she jogs and rides a total of 53 miles, we can set up the following equation:

x + 7.5 = 53

Solving for x, we can subtract 7.5 from both sides of the equation:

x = 53 - 7.5

x = 45.5

Therefore, Christy jogs 45.5 miles each day during training.

Answer 2

5 miles each day so 5×7=35 miles a week
