Question

a flyover is 500 m long a 10 m long bus crosses flyover at a speed of 30m/s find time taken by bus to cross it

Answer 1

$\huge\underline\mathfrak\red{Question:-}$

A flyover is 500 m long a 10 m long bus crosses flyover at a speed of 30m/s find time taken by bus to cross it.

$\huge\underline\mathfrak{Solution:-}$

Length of flyover = 500 m

Length= 10  m

So, total distance = 500+10 = 510 m

Now,

       speed of the bus= 30 m/s

       distance= 510 m

So, time taken by bus to cross it = distance / speed of bus

      =  510/30 

    = 17 seconds.

Hence, the time taken by the bus to cross the bridge is 17 seconds.

Answer 2

Answer:

The correct answer is 17 seconds.

Explanation:

Given :

Length of the flyover (L) = 500 m

Length of the bus (l) = 10 m

Total distance covered by the bus(d) = L + l = 500 + 10 = 510 m

Speed of the bus ( v) = 30 m/s

To be calculated = Time (t)

Formula to be used :

$time(t) = \frac{distace}{speed } = \frac{d}{v}$

Calculating time :

$t \: = \frac{510}{30} = 17seconds$

Hence, bus will take 17 seconds to cross the flyover.

Concept :

• The time formula is defined as the ratio of an object's distance travelled to its unit speed.
• The progression of events is referred to as time. This progression is made in such a way that it moves from the past to the present and then into the future.
• Speed is measured in metres per second, abbreviated as m/s. Because distance is measured in metres and time in seconds.
