Direction: Study the following information carefully and answer the questions that follow.
Car A: Car travels a certain distance in 6 hours and distance travelled by car A is 16.66% less than that travelled by car B .
Car B: Car travels a certain distance in 7 hour and 12 minutes with the speed of 50 km/h.
Car C: Car travels 400 km distance with twice the speed of car B

Car D travelled 40% more distance than that by car A in 10 hours, find the speed of car D.

Distance travelled by car D = 300 × 140% = 420 km
Speed of car D =420/10 = 42 km/h
Hence, option B is correct.
