Question

$\begin{array}{ccc}\text{v (metre/second)}& \text{t (second)}& \text{s(metre)}\\ 10& 2& a\\ -40& 2& b\\ -10& 2& c\\ -20& 2& d\end{array}$

s = vt gives the relation between distance, speed and time in the given equation. Select the statements that hold true.

• A. a = 20 m
• B. b = -80 m
• C. c = -20 m
• D. d = 40 m

Answer 1

Answer: (A), (B), (C)

The correct options are
A

a = 20 m

B

b = -80 m

C

c = -20 m

S = vt

In case of (a)

S = vt = 10 x 2 = 20

In case of (b)

S = vt = -40 x 2 = - 80

In case of (c)

S = vt = -10 x 2 = -20

In case of (d)

S = vt = -20 x 2 = -40
