B. 28 hours

Step-by-step explanation:

GIVEN :- Time taken by family to travel 600 km is 8 hours

CALCULATIONS :-

To calculate the time to travel 2100 km, we need to calculate distance traveled in 1 hour

Distance traveled in 1 hour = 600 km ÷ 8

                                             = 75 km

Time required to travel 2100 km = 2100 ÷ 75

                                                        = 28 hours

Therefore time required to travel 2100 km is 28 hours.
