Question

Car a travels 0.5 miles per hour faster than car

Answer 1

Answer:

Car B drives in 16 hours 1272 miles.

Step-by-step explanation:

Car A drives 1280 miles in 16 hours.

Speed = $\frac{Distance}{Time}$

The speed rate of car A = $\frac{1280}{16}$ = 80 miles per hour

Car A travels 0.5 miles per hour faster than car B.

∴ Speed of car B = 80 - 0.5 = 79.5 miles per hour

If car A drives 1280 miles in 16 hours.

∴ car B drives in 16 hours = 79.5 × 16 = 1272 miles

Car B drives in 16 hours 1272 miles.

Answer 2

Average speed for car a = 1280 / 16  =  80 mph
Car b travels at 80 - 0.5 = 79.5 mph.

Distance  car b will travel in same time  = 16*79.5 =  1272 miles.
