b). m(BD) = 6 units
Step-by-step explanation:
If ΔABC ~ ΔBDC,
a). Ratio of the corresponding sides of both the triangles will be equal.




Since Ratio of the corresponding sides are same, therefore, both the triangles are similar.

Answer:
60 km/hr.
Step-by-step explanation:
When Dad caught up the the time he had been driving was 4 hours and the time Mom had been driving was 1 + 4 = 5 hours.
They both drove the same distance, d km.
For Dad:

75 = d / 4
d = 75 * 4 = 300 km.
Mom took 5 hours to travel this distance, so
Mom's speed was 300 / 5 = 60 km/hr.
