### How long does it take me to get to the town centre from the

1 km away from the town there's a 120 km/h sign, 1/2 km away there is a 60 km/h sign, 1/3 km away there is a 40 km/h sign, 1/4 km away there is a 30 km/h sign, 1/5 km away there is a 24 km/h sign and 1/6 km away there is a 20 km/h sign.

If I travel at the speed limits, How long does it take me to get to the town centre from the 120km/h sign?

How far away is the 120-km sign? How far away is the 60-km sign? So how far did you go at 120 kph? How long did this take? (Subtract to find the distance; then divide to get the fraction of an hour.)

How far away is the 60-km sign? How far away is the 40-km sign? So how far did you go at 60 kph? How long did this take? (Subtract, and then divide.)

Keep going until you have found all the times. (They'll be fraactions.) Then add up the times to get the total.

Please write back (showing what you tried) if you get stuck. Thanks.
