Use the following equations to solve the problem.


final distance = initial distance + (speed × time)

df = di + vt

1.00 mi = 1.61 km


For an initial distance of 11.3 km, a speed of 35.0 miles per hour, and a time of 3.00 hours, what is the final distance in km?

(Points : 3)

49.3 km


180 km


116 km


76.5 km

35 mph = 56 km/h

Final distance = 11.3 + 56 x 3
Final distance = 179.3 km

The second option is correct.

d f = d i + v t
We know that: 1 mi = 1.61 km
d i = 11.3 km
v = 35 mph = 35 1.61 = 56.35 km/h
t = 3 h
d f = 11.3 km + 56.35 * 3 h = 11.3 km + 169.05 km = 180.35 km ≈ 180 km
Answer:
B ) 180 km
