Answer:

2 hours 55 minutes

Step-by-step explanation:

calculate time (T) using the relationship

T = [tex]\frac{D}{S}[/tex] ( D is distance , S is average speed )

T = [tex]\frac{210}{72}[/tex] = 2.9166... hours

to convert to hours and minutes multiply the decimal part by 60 , that is

0.9166.. × 60 = 55 minutes

then time taken to drive 210 Km is 2 hours 55 minutes
