Question

A train traveling at 54 miles an hour travles a certain distance in 3.5 hours. it takes 6 hours to cover the same distance if the speed is reduced by 9 miles per hour. true or false

a) True
b) False

Answer 1

false

Step-by-step explanation:

v1 = 54 mph

t1 = 3.5 hr

t2 = 6 hr

v2 = 54 - 9 = 45 mph

s1 = v1 × t1

= 54 × 3.5

= 189 miles

s2 = v2 × t2

= 45 × 6

= 270 miles

s1 ≠ s2, therefore statement is false
