Answer: Other Speed
First
Mr Lee and Mr Tan started driving from Point A in opposite directions. After driving for 4 hours, they were 660 km apart. If Mr Lee's driving speed was 100 km/h, find Mr Tan's average driving speed.

First
Timothy and Jane started jogging from the same place at the same time but in opposite directions along a straight road. Timothy's speed was 10km/h while Jane's speed was 8km/h. After jogging for 3 hours, how far apart were they?
xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
Total Speed = 10km/h + 8km/h
= 18km/h
= 18km/h
Total Distance = 18km/h × 3h = 54km

Given: Difference in Speed, Diverging Distance, Common Time
Answer: Fast or Slow Speed
First
Kerrine and Thompson started walking from the same starting point, but in opposite directions along a straight path.
Kerrine's average speed was 4 km/h more than Thomson's.
After walking for 3 hours, they were 40 km apart.
What was Kerrine's average walking speed.
xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
Difference in Distance = 4 km/h x 3 h = 12 km
Kerrine's Distance = (40km + 12km) / 2 = 26 km
Kerrine's Speed = 26 km / 3 h = 8 2/3 km/h

Second
Andy and Candy left their house at the same time and travelled in opposite directions.

Second
Andy and Candy left their house at the same time and travelled in opposite directions.
Candy drove at a speed of 16km/h slower than Andy.
30 minutes later, Andy arrived at his destination, while Candy stopped for a rest.
They were 100km apart then.
Find Andy's speed.
xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
Difference in Distance = 16 km/h x 1/2 h = 8 km
Andy's Distance = (100 km + 8 km) / 2 = 54 km
Andy's Speed = 54 km / 1/2 h = 108 km/h
