The total distance is increased by 25%. Ship C takes approximatel
Direction: Study the given line graph and pie chart carefully and answer the following questions accordingly.
Line graph shows the speeds (in km/h) of five different ships in a river and the speed of the water (in km/h) and pie chart shows the percentage of distance (in %) travelled by all the five ships
Question 1: The total distance is increased by 25%. Ship C takes approximately _______ hours more to cover new distance upstream than the time taken by ship A to cover the original distance downstream.(Approx)
A. 17 hours
B. 15 hours
C. 31 hours
D. 21 hours
E. None of these
Right Answer is: A
SOLUTION
New Distance = 3000 × 125% = 3750 km
Time taken by ship C to cover new distance (upstream) = (3750 × 20%)/24= 750/24 hours = 31.25 hours
Time taken by ship A to cover old distance (downstream) = 750/54 = 125/9 hours = 13.89 hours
∴ Required difference = 31.25 - 13.89 = 17.36 ≈ 17 hours
