The car will travel 387 ft in 5.00 s.
No. of kilometres = 5.00 s × (1 min/60 s) × (1 h/60 min) × (85.0 km/h) = 0.1181 km
No of feet = 0.1181 km × (1 mi/1.609 km) × (5280 ft/1 mi) = 387 ft
Among all of the choices listed, the only option that is a base would be the last one. As it is unique, whereby Hydrogen is not present in the front of the compound.
