First, express the mixed numbers as simple fractions:
1 3/5 = (1x5+3)/5 = 8/5
1 9/10= (10x1+9)/10 = 19/10
Add both:

The sum is greater than 3 and less than 4.

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:
speed = d / time
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.
