Question

14. River Yamuna was flowing at 200m level mark at Wazirabad Bridge in Delhi during rainy
season. If the level rises by 5cm every hour, after how many hours the level will reach 245m
level mark?
Explain very well

Answer 1

Answer:

after 900 hours

Step-by-step explanation:

because,

the initial level L1 = 200m

the final level L2 = 245m

So,

raised level L2 - L1 = 245-200

L= 45m

Given, it raises 5cm/hour

so, time taken = raised level/the raised heigh per hour

T = 45m/5cm {45m = 45×100 = 4500cm}

T= 4500/5

T = 900 hr
