Correct answer is B
distance = area under the graph.
= \(\frac{1}{2}\times 1 \times 4 ) + \frac{1}{2} \times (4+6)\times 1) + (6 \times 1.5) + (\frac{1}{2}\times(2 + 6)\times 0.5)\)
slope of the linear portion of the graph
length of the linear portion of the graph
area under the linear portion of the graph
area under the entire graph

Correct answer is C
Efficiency = \(frac{M.A×100}{V.R}\)
V.R = 6
40= \(frac{M.A×100}{6}\)
M.A = \(frac{6 ×40}{100}\)
M.a=2.4
M.A= \(frac{L}{E\)
E= \(frac{120}{2.4\)
E= 50
