always enjoys racing. One day, you

decide to take part in a race that has a

prize of $1 000 000! On the starting line,

the competitors are gearing up their cars,

all ready to race……

Click HERE to start.

You hold a steady grip on the steering

wheel of your car. Just then, the linesman

fires his pistol to signal the start of the

race! Will you:

Accelerate?

Trail behind the other cars?

After both shops sold an equal amountof flour, the ratio of rice that shop A has to shopB is 4:1. Find the amount of flour sold by theeach shop.a)76kg b)78kg c)49kg

You stamp down on the accelerator and

zoom ahead. In your side mirror you spot

a red Porsche gaining speed. It seems to

be trying to ram you from the back! Will

you:

Swerve to your right?

Stay where you are and just move straight?

You trail behind the unwavering line of

other cars. Suddenly, you see a sleek

Mercedes having some problem with his

engine. Will you:

Take the chance to smash it from behind?

Keep trailing behind the others?

The Mercedes, unable to take the full

impact, veers off the road and explodes in

a fiery ball of fire. You take its place

alongside the other cars. Will you:

Give your car a burst of acceleration?

Try to crash the other cars?

You swerve to the right just in time to

avoid the Porsche’s attack. Wiping sweat

from your face, you notice that the

Porsche has drawn level with you. It starts

to close in on you again! Will you:

Accelerate away?

Brake hard to allow the car to pass you?

What is the difference between theestimated and actual rate of completion perquestion?a) 14 seconds per questionb) 12 second per questionc) None of the above

THE END

Your car goes out of control and veers off

out of the road, crashing into a signpost.

You know that there is no hope for you to

win this race, so this is THE END for you.

Click here to start over again.

Solution

The answer is option 2. The estimated time per question is equal to the estimated time / (divide) by the number of questions: 31 / 3x60 divide by 100 = 10/3x60 divide by 100

= 10x20 divided by 100

= 200 divided by 100

= 2 min.

The actual time is equal to 3 hours (180 minutes). The actual time per question is equal to 180 min / (divide) by the number of questions: 180 / 100

= 1.8 min. The difference between actual time and estimated time

=2 minutes – (minus) 1.8 min:

2.0 - 1.8 = .2 min or .2 x 60 sec = 12 sec.

THE END

You decide to swerve left. Spinning your

steering wheel to the left, your car veers

right into the path of the incoming

Porsche! Too late, it rams into the side of

your car and your car is sent spinning off

the road, resulting in an explosion. Your

adventure is over. Click here to continue.

Solution

Jane has 3/10 of Mary’s books, since

Jane has 2 times less books than 3/5

(6/10) of Mary’s.

Jane:Cheryl:Mary 1unit= $528/(6+7+20)

6 : 7 : 20 = $16

Thus, Mary spent= $16 x 20 = $320

Solution

9.00AM to 1.00PM = 3hr 30min (3.5hr)

Hourly charge= 3.5 x $12 = $42

Distance charge= 16km x $0.13 = $2.08

Total fee= $42 + $2.08 = $44.08
