Question

Find the distance travelled with the following pairs of monomials as their speed and time respectively:
$(i) (25 a^{2} b^{2}, 50 b)$
$(i i) (12 a b c, 23 c d e)$
$(i i i) (5 c^{2} d^{2}, 4 a^{2} b^{2})$ [3 MARKS]

Concept: 1 Mark
Application: 2 Marks
Distance Travelled
$= S p e e d \times T i m e$

(i) Distance Travelled $= 25 a^{2} b^{2} \times 50 b = 1250 a^{2} b^{3}$
(ii) Distance Travelled $= 12 a b c \times 23 c d e = 276 a b c^{2} d e$
(iii) Distance Travelled $= 5 c^{2} d^{2} \times 4 a^{2} b^{2} = 20 a^{2} b^{2} c^{2} d^{2}$
