Question

Find the distance driven, if you drive at 60 mph for 3 1/2 hours. Round to the nearest whole mile.

A. 17 mi
B. 180 mi
C. 210 mi
D. 215 mi

Answer 1

The correct answer is 210 because if you go 60 miles an hour 60×3=180 and 60×1/2=30 so 180+30=210 so in total you go 210 miles

Answer 2

The answer is C. 210 mi

The velocity (v) is distance (d) divided by time (t):
v = d/t

v = 60 mph
t = 3 1/2 h = 3.5 h
d = ?

d = v * t
d = 60 * 3.5 = 210 mi
