Mathematics

Answer:

t = 44.73 s

Step-by-step explanation:

Given that,

The speed of a sound wave, v = 100 mph = 44.704 m/s

We need to find the time taken by the shockwave to reach 2 km i.e. 2000 m

We know that,

Speed = distance/time

So,

t=\dfrac{d}{v}\\\\t=\dfrac{2000}{44.704}\\\\t=44.73\ s

So, it will take 44.73 seconds to reach 2 km.

Kipish [7]

Answer:

17.98 square meters

Step-by-step explanation:

find the area of rectangle

length x width

6.2x1.8= 11.16

find area of triangle

base x height x 1/2

base= 6.2

height= 4-1.8= 2.2

area=2.2 x 6.2 x 1/2 = 6.82

add both together to get area of figure

6.82 + 11.16 = 17.98
