Problema Solution
the distance d traveled by a train varies directly as the time t that it travels. the train travels 60 km in 1/2 hour. how far will it travel in 2 hours.
Answer provided by our tutors
d is directly proportional to t
i.e. d1/d2 = t1/t2
d1=60km
t1=0.5 hr
t2=2 hrs
d2=60*2/0.5 = 120/0.5 = 240 kms [Ans.]
