S_A_V [24]3 years ago
4 0

Answer:

96 mph

Explanation:

There are a couple of ways of doing this, but I will just use a proportion.

first off 1 hour = 60 minutes.

So 144/90 = x/60 will give me the answer per 60 minutes of miles per hour.

cross multiply to get  90x = 8640

divide by 90 to get 96 miles per 60 minutes or 96 mph.

Hope this helped.

Luda [366]

Answer:

20 °C

Explanation:

Ideal gas law:

PV = nRT

Rearranging:

P / T = nR / V

Since n, R, and V are constant:

P₁ / T₁ = P₂ / T₂

488.2 kPa / T = 468 kPa / 281.15 K

T = 293.29 K

T = 20.1 °C

Rounded, the temperature was 20 °C.
