Tim's trip................

Solution

The trip to grandma’s takes 30 minutes. (If he were travelling at 7kph he would take an hour. Travelling at twice that speed halves the time.) This means that the home trip takes a third of an hour or 20 minutes. Tim’s total travelling time is therefore 50 minutes. If he spends 10 minutes with grandma he can still get home to watch his favourite programme.

Figure This

Ben has a box with a number in it that is greater 

than 7.

Moana has a box with a number in it that is 

less than 9.

Tom has a box with a number in it that is 

greater than 5.

They all have the same number. 

What is it?

Weights

Solution

Now 38 is not exactly divisible by 5 or 7. Hence both 5g and 7g weights are needed. Now 38 – 7 = 31, 38 – 2 x 7 = 24, and 38 – 3 x 7 = 17 are not divisible by 5. However, 38 – 4 x 7 = 10 = 2 x 5. So Dr Martin can use four 7g weights and two 5g weights.
