1. A vehicle leaves Leeds at 8.00am and

arrives in Newcastle at 10.30am. If the

distance is 140 km, what was the average

speed of the vehicle?

the answer is 13

step-by-step explanation:

5*5=25

12*12=144

25+144=169

169^2=13

11.2

step-by-step explanation:

when doing tangent the tangent of the angle is equal to the opposite side from the angle over the adjacent side to the angle.

tan43 = x / 12

move 12 over by multiplying each side by 12

12tan43 = x

x = about 11.2
