Question 1110001
At 09 00 car A starts its journey and traveling at 70 km/h
 at 10 30 car B started from the same place and traveled steadily on the same road.
 Car B took 3 1/2 h to catch up with car A.
 Find the speed of Car B.
let b = speed of car b
:
When car B catches up with A, the will have traveled the same distance
Write a distance equation:  dist = speed * time
Car A traveled 1.5 hrs longer than car B. Car A traveled: 3.5 + 1.5 = 5 hrs
:
B's dist = A's dist
3.5b = 70(5)
3.5b = 350
b = 350/3.5
b = 100 km/hr
