a train travels 290 km in 4 hours and 1 hour travels 180 km in 3 hours. what is the ratio of the distance travelled by the train to the distance travelled by the car in 1 hour?
Answers
Step-by-step explanation:
GIVEN:
distance covered by train = 290 km
time taken by train = 4 hours
distance covered by car = 180 km
time taken by car = 3 hours
TO FIND: ratio of distance traveled by train and car in one hour
solution:
we can use average speed to find ratio because of time being the same in both , i.e. 1 hour
if we find the average speed of train and car, we can then divide the figure to find the ratio we need.
average speed of train = 290 km/4 hour
= 72.5 km per hour
average speed of car = 180 km /3hour
= 60km per hour
now we put the average speed in ratios so we ultimately get the ratios of distance traveled by train and car in one hour.
the answer is 72.5/60 = 1.208 or 29/24
