200 km/h
1) Gathering the data
Car 1: x
Car 2: x-16
time: 2 hours
2) Considering the formula that relates to Speed, Time, and Displacement, we can write assuming their speeds are at a constant rate.
• The speed of Car 1 and Car 2 can be added so that we can plug them into that formula.
,
• We can then write and cross multiply those ratios.

3) Hence, the slower car is at 216 -16 = 200 km/h
