**Step-by-step explanation:**

**Question:**

Two rowing teams are having a race. Boat A had a head start, crossing the start line first and traveling at a speed of 3 meters per second. Boat B waited and then crossed the start line 6 seconds after Boat A. The speed of Boat B was 4.8 meters per second.

Part A- Write two equations, one for Boat A and one for Boat B. In both equations, let t equal the time in seconds since Boat A crossed the start line and d equal the distance traveled in meters.

Part B- Solve the system of equations from part A. show your work**

**

**Answer:**

**A. Equations **

**b.**

**Step-by-step explanation:**

**For Boat A:**

**For Boat B:**

Boat B waited 6 seconds later. So, the time is:

**Solving (a): Equations**

**Speed is calculated as:**

**For Boat A:**

**Make d the subject**

**For Boat B:**

**Make d the subject**

**Substitute t - 6 for T**

**Hence, the equations are:**

**Solving (b): The value of d**

**Substitute 3t for d in the second equation**

**Collect like terms**

**Solve for t**

**Recall that:**

**Next, calculate the distance:**

**So:**

Boat A travels for 16 seconds

Boat B travels for 10 seconds

The distance is 48km

**Answer:**

yes
