Question

Car a travels 0.5 miles per hour faster than car

b. if car a drives 1280 miles in 16 hours how far would car b drive in the same amount of time

Answer 1

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.

Answer 2

Car B drives in 16 hours 1272 miles.

Explanation:

Car A drives 1280 miles in 16 hours.

Speed =
`(Distance)/(Time)`

The speed rate of car A =
`(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.
