Question

The distance traveled can be calculated using the formula D=s⋅t where s is the speed and t is the total time. Which of the situations below represent a total distance of 120 km? Select all that apply.

A) 40 km/hr for 3 hours
B) 60 km/hr for 2 hours
C) 30 km/hr for 4 hours
D) 25 km/hr for 5 hours

Answer 1

A, B, C

Explanation:

The given formula tells you that to find distance, you multiply speed by time. When you do that, you get:

A) (40 km/h)(3 h) = 120 km

B) (60 km/h)(2 h) = 120 km

C) (30 km/h)(4 h) = 120 km

D) (25 m/h)(5 h) = 125 km

Choices A, B, C each total 120 km.
