Answer:
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.
