Answer: The distance traveled by Roberto and his dad is 70 km

Explanation:

We are given:

Roberto and his dad drove from town A to town B.

[tex]d_1[/tex] = Distance traveled by Roberto and his dad during this is 50 km (as per the image)

Then, both of them came back by taking a straight short cut.

[tex]d_2[/tex] = Distance traveled by Roberto and his dad during this is 20 km (as per the image)

We know that, distance shows an additive property. This means that distance can be added.

Total distance traveled = [tex]d_1+d_2=(50+20)km=70km[/tex]

Hence, the distance traveled by Roberto and his dad is 70 km
