Answer:
40
Step-by-step explanation:
The scale factor of 5 to the side measuring 8 means that you multiply that side by the scale factor.
Basically, the equation would go like this:
Original Side Length: x
Scale Factor: y
New Side Length: z
xy=z
If we plug in our numbers, we get:
8*5=z
40=z
<u>40</u>
The reaction times form a straight line with gradient of 60/140 = 3/7 m/kph
Reaction time at 130 kph = 3/7 x 130 = 390/7 = 56 m to nearest whole number
