The correct Answer is:
To solve the problem step by step, we will define the variables and set up equations based on the information given. ### Step 1: Define Variables Let: - \( W \) = time taken to walk one way (in minutes) - \( R \) = time taken to ride one way (in minutes) ### Step 2: Set Up Equations From the problem, we have two scenarios: 1. Walking one way and riding back takes a total of 37 minutes: \[ W + R = 37 \quad \text{(Equation 1)} \] 2. Walking both ways takes a total of 55 minutes: \[ 2W = 55 \quad \text{(Equation 2)} \] ### Step 3: Solve for \( W \) From Equation 2, we can find \( W \): \[ W = \frac{55}{2} = 27.5 \text{ minutes} \] ### Step 4: Substitute \( W \) into Equation 1 Now, substitute \( W \) back into Equation 1 to find \( R \): \[ 27.5 + R = 37 \] \[ R = 37 - 27.5 = 9.5 \text{ minutes} \] ### Step 5: Calculate Time for Riding Both Ways To find the time taken to ride both ways, we calculate: \[ 2R = 2 \times 9.5 = 19 \text{ minutes} \] ### Final Answer Thus, the time it would take to ride both ways is **19 minutes**. ---
