**Answer: **a) 2(x + 5)km

**2. Which of the following quadratic equation describe the speed of Raj’s car? **

a) x^{2} – 5x – 500 = 0

b) x^{2} + 4x – 400 = 0

c) x^{2} + 5x – 500 = 0

d) x^{2} – 4x + 400 = 0

**Answer:** c) x^{2} + 5x – 500 = 0

**CASE STUDY 2: **

The speed of a motor boat is 20 km/hr. For covering the distance of 15 km the boat took 1 hour more for upstream than downstream.

**1. Let speed of the stream be x km/hr. then speed of the motorboat in upstream will be **

a) 20 km/hr

b) (20 + x) km/hr

c) (20 – x) km/hr

d) 2 km/hr

**Answer:** c) (20 – x)km/hr

**2. What is the relation between speed ,distance and time? **
