Question

Jolene drove 280 miles on Monday in 5 hours, 360 miles on Tuesday in 3 hours, and 180 miles on Wednesday in 2 hours.
On which day was her speed maximum?

• A. Tuesday
• B. Monday
• C. Speed was the same on all three days
• D. Wednesday

Answer 1

The correct option is A Tuesday

Distance traveled on Monday = 280 mi

Time taken = 5 h

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

$=\frac{280}{5}$

= 56 mph


Distance traveled on Tuesday = 360 mi
Time taken = 3 h

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

$=\frac{360}{3}$

= 120 mph


Distance traveled on Wednesday = 180 mil
Time taken = 2 h

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

$=\frac{180}{2}$

= 90 mph

We know, 56 < 90 < 120

Hence, her speed was the maximum on Tuesday.
