Answer:
B. 28 hours
Step-by-step explanation:
GIVEN :- <em>Time taken by family to travel 600 km is 8 hours</em>
CALCULATIONS :-
<em>To calculate the time to travel 2100 km, we need to calculate distance traveled in 1 hour</em>
<em>Distance traveled in 1 hour = 600 km ÷ 8</em>
<em> = 75 km</em>
<em>Time required to travel 2100 km = 2100 ÷ 75</em>
<em> = </em><em>28 hours</em>
Therefore time required to travel 2100 km is 28 hours.
