The outward rush of gases from the bomb’s site of origin can be as high as what?
100 mph
500 mph
2000 mph
7000 mph

7000mph

Explanation: In an explosion the outward rush of gases differentiates the type of explosive that is being used, for example, from gas explosives the ranges are from 1800 m/s to 3000m/s, and for solids, the range is 4000m/s to 10300 m/s, the options seem to be in the range of the gas explosives, so i will consider that the question is asking about these type of explosives.

Now, the units in the options are in mph, this stands for miles per hour, so we must change the units in the ranges:

1m = 0.000621371 miles

1 hour = 3600 seconds.

Then, for gas explosives we have:

Then 1800m/s = 1800*0.000621371*3600 = 4026.48408 mph

3000m/s = 3000*0.000621371*3600 = 6710.8068 mph

So we can see that the biggest recorded velocities for gas explosives is around 7000mph. then the correct option is the last one, 7000mph
