You could multiply that fraction by (1 hour / 3,600 seconds) .
(18,000 mile / 1 hour) x (1 hour / 3,600 second) =
(18,000 x 1) / (1 x 3,600) (mile-hour) / (hour-second) =
(18,000 / 3,600) (mile / second) = <span>5 mile/second

Answer:
17.8
Step-by-step explanation:
First, round the two. umbers to the nearest the th, or the first number past the decimal. 19.28 rounds to 19.3 (round up because 8 is bigger than 5) and 1.546 rounds to 1.5 (round down because 4 is smaller than 5). Then subtract. 19.3 - 1.5 = 17.8
1)X=4
2)X=3
3)X=20
1)X=7.25
2)X=1.5
3)X=41
Answer:
Cyclist A
Step-by-step explanation:
given,
velocity of Bicyclist A = 17 mil/hr
acceleration = 32 miles/hr²
velocity of Bicyclist B = 20 miles/hr
acceleration = 2 miles/hr²
which cyclist in front after = 15 minutes = 1/4 hour
using equation of motion for cyclist A
s = 5.25 mile
using equation of motion for cyclist B
s = 5.0625 mile
Cyclist A will be in-front after 15 minutes
